Tumor de células gigantes del vaina tendinosa (nódulo en un dedo o pulgar)

A giant cell tumour of tendon sheath is a common, benign (non-cancerous) lump on a finger or thumb. What causes it, how it is diagnosed and removed, and how often it comes back.

Bajo el microscopio, el tumor de células gigantes del recubrimiento tendinoso está formado por agrupaciones de células gigantes multinucleadas (las células oscuras y de aspecto abultado) mezcladas con células mononucleadas más pequeñas. Es una lesión benigna; es precisamente este aspecto de células gigantes el que le da el nombre a la misma. Kieran Hirpara 4.0

Qué está sintiendo

Probablemente haya notado un bultito duro y pequeño en uno de sus dedos o en el pulgar. Por lo general no duele al tacto, y suele estar fijo en su lugar, sin moverse bajo la piel. El bulto puede ser liso o tener una forma ligeramente irregular.

La mayoría de estos bultos se localizan cerca de una articulación. La articulación situada al final del dedo es un lugar frecuente; el bulto puede aparecer en la parte dorsal, frontal o lateral del dedo. El dedo índice se ve afectado con mayor frecuencia que los demás.

Para muchas personas, el bulto en sí mismo no supone ningún problema. No siempre causa dolor, pero cuando aparece, suele localizarse justo en el bulto o en la articulación cercana. Algunas personas notan que el dedo se traba o se bloquea, o que hay hinchazón alrededor de la articulación. Un número reducido de pacientes siente hormigueo o entumecimiento si el bulto presiona algún nervio cercano.

Dado que el bulto se encuentra cerca de los tendones —las estructuras que permiten el movimiento del dedo—, ciertas tareas cotidianas pueden volverse incómodas. Le resultará más difícil agarrar la tapa de un frasco, sostener un bolígrafo con comodidad, escribir en el teclado o abrocharse la ropa. Cualquier acción que doble o comprima el dedo en la zona del bulto lo hará más evidente.

Estos bultos crecen lentamente. Muchas personas conviven con ellos durante meses o incluso años antes de acudir al médico. No existe un patrón típico de empeoramiento por la noche o al despertar, y ninguna de sus actividades lo agrava.

Algunos datos importantes: este tipo de bulto es benigno, es decir, no es cáncer ni se propaga a otras partes del cuerpo. También es frecuente: aparece más a menudo en mujeres que en hombres, y suele manifestarse entre los 32 y los 51 años, aunque puede aparecer antes o después. Normalmente no está relacionado con ninguna lesión.

Lo fundamental que debe acordar con su cirujano es la extirpación completa del bulto, pues estos bultos pueden volver a aparecer si queda algún tejido residual.

¿Qué está ocurriendo realmente?

Su dedo cuenta con dos cordones delgados, llamados tendones, que van desde la palma hasta la punta del dedo. Funcionan como los hilos que mueven los dedos de una marioneta: cuando el músculo se contrae, el tendón se desliza y el dedo se dobla. Cada tendón se desliza dentro de una vaina lisa, similar a una junta que rodea una tubería en movimiento, la cual facilita dicho deslizamiento.

El tumor de células gigantes de la vaina tendinosa consiste en un crecimiento excesivo del tejido que forma dicha vaina. El nombre suena alarmante, pero describe cómo se ve ese tejido bajo el microscopio, no su función. Es benigno, no es cáncer. El bulto crece lentamente a partir de la propia vaina, por eso se siente fijo en su lugar en lugar de moverse bajo la piel.

A medida que el bulto aumenta de tamaño, ejerce presión sobre los tejidos circundantes. Eso explica la mayoría de los síntomas que usted ha notado. La presión sobre el tendón puede provocar bloqueos o atrapamientos, así como hinchazón alrededor de la articulación cercana. La presión sobre un nervio puede causar hormigueo o entumecimiento. El dolor es menos frecuente de lo que cabría esperar; de hecho, muchos de estos bultos nunca causan dolor alguno.

Existen dos patrones generales. La mayoría de los bultos son un único nódulo bien definido, con bordes claros, parecido a un guisante dentro de una cápsula. Los demás están formados por dos o más fragmentos separados que no se unen entre sí; esto es importante porque dichos fragmentos dispersos son más difíciles de extirpar por completo. En ocasiones, el bulto presiona el hueso adyacente, dejando una pequeña hendidura en lugar de penetrar en él.

Nadie sabe con certeza por qué se inicia este crecimiento excesivo. La teoría aceptada es que el tejido de la vaina reacciona a alguna irritación y comienza a multiplicarse; los genes también podrían desempeñar un papel. Las lesiones rara vez son el desencadenante.

En resumen: el bulto es un problema localizado en un punto específico de su dedo, y el objetivo del tratamiento es extirparlo por completo para evitar que vuelva a crecer.

¿Qué podemos hacer al respecto?

El Dr. Kieran Hirpara, cirujano de extremidades superiores en el Mater Private Hospital Rockhampton, comienza con las opciones menos invasivas que se adapten a su condición. Por lo general, los pacientes son derivados a nuestra clínica por su médico de cabecera; si un fisioterapeuta le ha sugerido consultarnos, igualmente necesitará una derivación de su médico de cabecera para poder acceder al reembolso de Medicare. En su primera visita, tomamos su historia clínica, examinamos el dedo y, si es necesario, programamos estudios de imagen como una tomografía para confirmar de qué se trata el bulto.

En el caso de un bulto como este, hay pocas medidas que pueda intentar en casa para hacerlo disminuir. Si el bulto interfiere con sus movimientos o dificulta ciertas tareas, podríamos sugerirle cambiar temporalmente la forma en que utiliza esa mano. La terapia de la mano tiene como objetivo mantener el dedo en movimiento sin molestias y aliviar cualquier irritación en el tendón cercano al bulto. Por lo general, damos a este tratamiento una oportunidad razonable antes de considerar otras opciones.

Estos bultos no son causados por inflamación, por lo que los analgésicos y antiinflamatorios no logran reducirlos. Si el bulto le causa molestias, los analgésicos simples pueden ayudar a aliviar los síntomas mientras espera la evaluación médica.

La mayoría de estos bultos no desaparecen por sí solos; el tratamiento aceptado es extirparlo por completo. Dado que el bulto se origina en la vaina tendinosa, la cirugía busca eliminar tanto el bulto como el pequeño fragmento de dicha vaina al que está adherido. Es importante extirpar esa zona de unión: cuando se hace así, en promedio, estos bultos no vuelven a aparecer durante unos tres años. Si queda algún tejido residual, el bulto puede reaparecer; por este motivo, aproximadamente una de cada siete personas necesita una segunda operación. Los bultos compuestos por dos o más fragmentos separados tienen mayor probabilidad de reaparecer que los bultos únicos, por lo que en esos casos tomamos precauciones adicionales.

La decisión quirúrgica se toma conjuntamente entre usted y nosotros. Si el bulto es pequeño, no le causa dolor y no le genera molestias, observarlo puede ser una opción razonable. Si, en cambio, está creciendo, interfiere con sus movimientos, presiona algún nervio o le causa molestias diarias, lo habitual es proceder a su extirpación. La propia operación cuenta con una página dedicada en la que se explica en qué consiste y cómo es el proceso de recuperación.

Qué esperar

El pronóstico de este bulto es estable, sin cambios drásticos. Es benigno, por lo que no se propaga a otras partes del cuerpo. Además, crece lentamente; la mayoría de los bultos no desaparecen por sí solos. Si se deja sin tratar, generalmente permanece igual o sigue creciendo poco a poco; por eso muchas personas optan finalmente por extirparlo.

Lo principal a tener en cuenta es la posibilidad de que el bulto vuelva a aparecer. Aproximadamente una de cada siete personas necesita una segunda operación, ya que queda algo de tejido tras la primera intervención. Cuando vuelve a aparecer, suele ser dentro de los 36 meses posteriores a la primera extirpación. Algunos tipos de bultos tienen mayor tendencia a reaparecer: aquellos compuestos por dos o más partes separadas, y los que han crecido dentro del tendón o de la cápsula articular, es decir, la cubierta que rodea la articulación. Si el suyo pertenece a alguno de estos tipos, su cirujano lo vigilará más de cerca después de la operación.

Cuando el bulto se extirpa por completo, los resultados se mantienen estables con el tiempo. Las personas sometidas a esta cirugía suelen conservar un buen uso de la mano; en un grupo estudiado, la función de la mano alcanzó el 92 % del valor normal. Algunas personas de ese grupo presentaban un bulto similar situado más profundamente en una articulación; tras ser tratadas mediante cirugía mínimamente invasiva, permanecieron libres del bulto casi siete años después. En el caso de otro tipo de bulto, menos frecuente, localizado en la vaina tendinosa, la extirpación del bulto y de su punto de anclaje ha evitado cualquier reaparición durante un promedio de tres años.

Si el bulto resulta ser del tipo que se extiende más ampliamente por la vaina tendinosa, o si vuelve a aparecer tras la cirugía, aún existen opciones de tratamiento. La radioterapia, un tratamiento dirigido con rayos X, puede a veces controlar el bulto sin afectar el funcionamiento normal de la mano.

En resumen, la situación real es la siguiente: el bulto no desaparecerá por sí solo; la extirpación funciona bien en la mayoría de los casos; y lo principal a vigilar en los años posteriores es la reaparición del bulto, generalmente dentro de los primeros tres años.

Cuándo consultar a un especialista

Acuda a su médico de cabecera si nota un bulto duro en un dedo o pulgar que no desaparece después de unas semanas, o si este crece lentamente. Solicite una evaluación especializada si el bulto causa interferencias al mover el dedo, si la articulación circundante está inflamada, o si experimenta hormigueo o entumecimiento en el dedo, lo cual podría indicar que el bulto está comprimiendo un nervio. El dolor es menos frecuente en esta afección; sin embargo, si el bulto se vuelve sensible al tacto o dificulta sus actividades laborales o cotidianas, también merece ser evaluado. Estos bultos son benignos, por lo que no constituyen una emergencia ni se propagan a otras zonas. La razón principal para no esperar años es que cuanto más tiempo permanezca el bulto junto al tendón, mayor es la presión que ejerce sobre las estructuras circundantes; además, un bulto más pequeño es más fácil de extirpar por completo.

En mayor profundidad

Esta sección profundiza más de lo necesario para que usted tome sus propias decisiones de tratamiento. El tumor de células gigantes de la vaina tendinosa merece ser leído con atención, ya que su problema principal es la recurrencia; además, la evidencia indica que dicha recurrencia depende más de la biología del tumor en sí que de cómo se realice su extirpación.

La recurrencia es una propiedad del tumor, no solo de la cirugía

La explicación instintiva para el regreso de un bulto es que quedó algo del mismo. Sin embargo, una revisión sistemática de 605 casos concluyó lo contrario: la biología intrínseca del tumor parece desempeñar un papel más fundamental en la recurrencia que la ubicación del tumor o su invasividad local. Los autores solicitaron la realización de estudios prospectivos más amplios para identificar qué tumores son propensos a la recurrencia [1].

Esta información resulta verdaderamente útil antes de una operación. La recurrencia tras una escisión realizada correctamente constituye un comportamiento característico de este tumor, y no una señal de que algo salió mal.

El tratamiento es opcional; no hacer nada también es una opción válida

Es fácil olvidar esto una vez que se planifica una operación. El principio del tratamiento de primera línea es la resección completa; sin embargo, el tratamiento nunca es urgente, y la indicación para intervenir debe evaluarse en función de los síntomas, la progresión de la enfermedad, la ubicación del tumor y sus propias circunstancias [4].

En el caso de un nódulo pequeño, indoloro y de crecimiento lento, observarlo sin intervenir es una elección legítima. El tumor es benigno y no se disemina; por lo tanto, los motivos para operar se relacionan con la función, el tamaño y el grado de molestia que provoca, no con el riesgo de peligro.

Pero dos factores quirúrgicos sí son relevantes

La biología no lo explica todo. En 941 pacientes con tumor de células gigantes tenosinovial de tipo localizado, los factores asociados a la recurrencia tras la resección fueron un tamaño tumoral mayor y el tratamiento inicial mediante artroscopia. Dadas las tasas de complicaciones relativamente bajas y los buenos resultados funcionales, los autores recomiendan un abordaje abierto con resección completa siempre que sea posible, para reducir la recurrencia en casos de alto riesgo [2].

Por otro lado, se ha demostrado que la excisión artroscópica resulta eficaz para el tipo localizado en cuatro articulaciones, según un estudio realizado en 1,448 pacientes; en cambio, para el tipo difuso, la sinovectomía artroscópica solo ha mostrado eficacia en la rodilla [3].

Para conciliar ambos enfoques: en lesiones pequeñas, localizadas y bien delimitadas, cualquiera de los dos métodos puede ser adecuado. No obstante, a medida que el tamaño aumenta o en el caso del tipo difuso, la excisión abierta completa cuenta con mayor respaldo. La razón es de índole mecánica: este tumor se extiende en forma de “frondas” alrededor de tendones, nervios y articulaciones; las zonas que más fácilmente se pasan por alto son aquellas situadas detrás de estructuras que deben ser levantadas e inspeccionadas directamente.

¿Por qué es importante la nomenclatura?

Actualmente, esta afección se denomina tumor de células gigantes tenosinovial, término que abarca tanto la forma localizada en la mano como la forma difusa intraarticular anteriormente conocida como sinovitis villonodular pigmentada [4]. Se trata de la misma entidad, aunque en distintas localizaciones y con patrones de crecimiento diferentes.

Es importante tener esto en cuenta si investiga sobre el tema, ya que las búsquedas le mostrarán información referente a rodillas y caderas que describe la enfermedad en su forma difusa. Las tasas de recurrencia mencionadas para esta forma difusa son considerablemente más altas que las correspondientes a lesiones digitales localizadas. Aplicar esos datos de rodillas a un nódulo en el dedo podría sobreestimar el riesgo real.

Posición de la radioterapia en el tratamiento

En casos de enfermedad difusa que ha recidivado o que no puede resecarse por completo, a veces se considera la radioterapia adyuvante. Un metaanálisis determinó que la sinovectomía abierta, o la sinovectomía combinada con radioterapia perioperatoria, se asociaba con una tasa reducida de recurrencia en la sinovitis villonodular pigmentada difusa; no obstante, se requieren estudios prospectivos a largo plazo y de gran escala para confirmar dichos resultados [5].

En el caso de tumores digitales localizados, que constituyen la gran mayoría de los casos en la mano, esto no es aplicable. Este tipo de tumor pertenece al extremo del espectro caracterizado por afectación difusa, recurrencia y localización articular; se menciona aquí únicamente porque una búsqueda por el nombre de esta patología arrojará resultados relacionados con ella.

Qué no es

A pesar del nombre, se trata de un tumor benigno. No se disemina a otras partes del cuerpo. La palabra “tumor” tiene una connotación que aquí no le corresponde; la preocupación por su reaparición se refiere a la necesidad de realizar cirugías locales repetidas, a la rigidez articular y a la proximidad con los nervios, no al cáncer.

Anatomy & Pathophysiology

Epidemiology & Demographics

  • Giant cell tumours of tendon sheath (GCTTS) are the second most common benign proliferative tumours in the upper extremities after ganglion cysts [65].
  • GCTTS are usually slow-growing, painless, benign, and consist of soft tissue [65].
  • GCTTS are most commonly found in the fingers and among women in their fourth and fifth decades [65].
  • In a systematic review of 605 patients, the male-to-female ratio for GCTTS of the digits was 1:1.47 [11].
  • In a study of 64 cases, the male-to-female ratio for GCTTS was 1:1.66 [25].
  • In a series of 12 patients, the mean age for GCTTS was 29.5 years, ranging from 10 to 53 years [23].
  • In a study of 64 cases, the age of patients ranged from 15 to 77 years with a mean age of 45 years [25].

Clinical Presentation & Location

  • GCTTS are usually asymptomatic, but as the tumour grows, patients may present with swelling, pain, and limitation of movement [65].
  • In a systematic review of 605 patients, pain was reported in 15.7% of cases and sensory disturbances in 4.57% [11].
  • In a systematic review of 605 patients, a definite history of trauma was recorded in 5% of lesions [11].
  • In a systematic review of 605 patients, the most frequent tumour location was the index finger (29.7%) [11].

  • In a series of 12 patients, the most common presentation was with a mass over the hand, with a predilection to the thumb (n=7) [23].

Morphology & Histology

  • Type I GCTTS are defined as nodular or multinodular lesions surrounded by a capsule [65].
  • Type II GCTTS are defined as tumours with no connective tissue membrane and satellite, diffuse, or multicentric nodules [65].
  • In a systematic review of 605 patients, Type I tumours (single lesions) were detected in 78.7% of cases [11].
  • In a systematic review of 605 patients, Type II tumours (two or more distinct tumours that were not joined together) were detected in 21.3% of cases [11].
  • Microscopically, all GCTTS tumors contained multinucleated giant cells, histiocytes, and haemosiderin deposits [25].
  • Macroscopically, the average size of GCTTS tumors was 1.35 cm, with a range of 0.3 cm to 5 cm [25].

Pathogenesis & Etiology

  • GCTTS originate from the synovial membrane, tendon sheath, or synovial bursa [65].
  • The pathogenesis of GCTTS remains unclear [65].
  • Inflammation resulting from reactive or regenerative hyperplasia is the generally accepted theory of pathogenesis for GCTTS [65].
  • Genetic factors have been observed in previous studies regarding GCTTS pathogenesis [65].

Imaging & Local Invasion

  • Radiography can be helpful in evaluating cortical destruction but is not helpful in the definitive diagnosis of GCTTS [65].
  • Magnetic resonance imaging (MRI) is the most useful examination for the diagnosis and treatment planning of GCTTS [65].

  • In a study of 64 cases, involvement of the neurovascular bundle was presented in 7 patients (10.9%) [25].

Classification

  • Giant cell tumour of tendon sheath (GCTTS) is classified into two main types based on whether the entire tumour is surrounded by one pseudocapsule [56].
  • Type I GCTTS consists of single lesions [11].
  • Type II GCTTS consists of two or more distinct tumours that are not joined together [11].
  • Type I tumours were detected in 78.7% of patients in a systematic review of 605 patients [11].
  • Type II tumours were detected in 21.3% of patients in a systematic review of 605 patients [11].
  • In a prospective study of 43 cases, none of the 30 Type I tumours recurred [56].
  • In a prospective study of 43 cases, recurrence occurred in five out of 13 Type II tumours [56].
  • Second recurrences were observed with Type II B and C tumours but not with Type II A tumours [56].
  • Type II tumours are associated with a higher risk of recurrence compared to Type I tumours [11].
  • The Al-Qattan classification is used to classify GCTTS lesions based on capsule thickness, lobulation, satellite lesions, and diffuse or multicentric nature [23].

Clinical Presentation

  • Giant cell tumors of the tendon sheaths in the hand are benign lesions where recurrence is the primary risk [2].
  • Giant cell tumors of the synovial sheaths in the hand are benign lesions in which recurrence is the primary risk [3].
  • Pigmented villonodular synovitis and giant-cell tumor of tendon sheath are benign synovial neoplasms with the potential for local recurrence [38].
  • Patients with giant cell tumor of tendon sheath may present with a discrete mass or with joint swelling, pain, or locking or catching [26].
  • The most frequent tumour location for giant cell tumour of tendon sheath of the digits is the index finger, accounting for 29.7% of cases [11].
  • In a series of 91 finger tumors, 31 occurred at the distal joints, with 18 on the dorsal aspect and 13 distributed about evenly on the radial, ulnar, and volar aspects [22].
  • The tumors were usually firm, lobulated, and non-tender [22].
  • The masses were somewhat fixed [22].
  • Pain was reported in 15.7% of cases of giant cell tumour of tendon sheath of the digits [11].
  • Sensory disturbances were reported in 4.57% of cases of giant cell tumour of tendon sheath of the digits [11].
  • A definite history of trauma was recorded in 5% of lesions [11].
  • The male-to-female ratio for giant cell tumour of tendon sheath of the digits was 1:1.47 [11].
  • The mean age for giant cell tumour of tendon sheath of the digits ranged from 32 to 51 years [11].
  • Type I tumours (single lesions) were more frequently detected (78.7%) than type II tumours (two or more distinct tumours that were not joined together) (21.3%) [11].
  • Type II tumours were associated with higher recurrence rates [11].
  • The overall recurrence rate for giant cell tumour of tendon sheath of the digits was 14.8% [11].
  • The duration of symptoms for finger tumors ranged from two weeks to fifteen years, with an average duration of thirty-eight months [22].
  • In a series of 12 patients, the mean age was 29.5 years, ranging from 10 to 53 years [23].
  • Radiological changes in the form of bony indentation were seen in only 2 cases out of 12 [23].
  • Direct involvement of the extensor tendons, flexor tendons, or joint capsule puts patients in a high-risk category with respect to recurrence [21].

Investigations

  • MRI findings and location might help in the diagnosis of tenosynovial giant cell tumors, but careful assessment is mandatory, especially in unusual locations [84].
  • Radiologists should be familiar with the imaging characteristic of giant cell tumors of the mobile spine with invasion of adjacent vertebrae [87].

Treatment

Surgical Excision

  • Complete surgical resection is the treatment of choice for most patients with tenosynovial giant cell tumors [7].
  • Total surgical excision ensuring removal of the attachment site (flexor sheath/palmar fascia) resulted in no local recurrences at a mean follow-up of 3.2 years [8].
  • En bloc resection and matched nonvascularized toe phalangeal transfer resulted in a functional tumor-free digit with a low complication rate and no recurrences for Campanacci Grade 2 or 3 giant cell tumors of the phalanges [17].
  • Repeated curettage with adjuvants eventually resulted in the cure for all patients and is a reasonable treatment for both primary and recurrent GCT of the small bones of the hands and feet [68].
  • Intralesional excision with local adjuvant therapy is recommended for the treatment of giant cell tumor of bone because it results in a good functional outcome compared to extralesional excision [63].
  • Intralesional excision with cautery and methylmethacrylate provides a reliable method of treatment of giant cell tumors with good long-term functional results [37].
  • Intralesional excision remains a viable, and likely the standard, mode of treatment for most giant cell tumors of the distal radius unless there is extensive bone loss [6].
  • Intralesional excision appears to be more appropriate for the treatment of local lesions (eg, Grades 1 and 2) than Grade 3 GCTs of the distal radius [27].
  • Both curettage and resection/amputation are acceptable treatment options for the rare condition of giant cell tumour of bone in the hand, with a need to individualize treatment decisions based on the site and extent of disease to minimize treatment morbidity while maximizing disease control [4].
  • The distal ulna may be widely resected with or without stabilization of the residual ulnar stump, yielding satisfactory local disease control and functional outcome [24].
  • Reconstruction after wide excision by nonvascularized fibular graft is a viable alternative for giant cell tumors of the lower end of radius though it is a challenging procedure and may be accompanied by major complications [73].
  • The use of a massive biocompatible bipolar unconstrained prosthesis is a viable treatment option for distal radius reconstruction after en-bloc resection of a giant cell tumour, offering rapid functional improvement without donor-site morbidity [62].
  • This is a simple and effective modality of reconstruction after resection of distal radial tumors [13].
  • Aggressive and malignant bone tumors of the second through fifth metacarpals generally require en bloc bone excision [18].
  • It is essential that an adequate, safe margin of normal tissue first be excised en bloc with the tumor for aggressive and malignant bone tumors of the second through fifth metacarpals [18].
  • Wide en bloc excision of soft tissue sarcomas with negative margins is required to achieve local control of the lesion [18].
  • At a minimum, aggressive soft tissue tumors, such as bone tumors, require ray resection or removal of multiple rays [18].
  • Central palmar lesions more likely require sacrifice of three rays; those on the border are more likely than those in the center to be salvageable by removing just two rays [18].
  • In the presence of proximal, broader, and larger lesions, all four digits or the entire hand may have to be sacrificed to save the patient [18].
  • If a malignant tumor has broken into the midpalm and extends across the metacarpals, removal of all digital rays may be needed to gain an adequate soft tissue margin [18].
  • If a tumor extends proximally from the metacarpal level, a more proximal level of hand, wrist, or forearm amputation is required for safe tumor management [18].
  • Malignant soft tissue tumors in the palm or carpal tunnel often require at least partial hand amputation [18].
  • Below-elbow amputation is necessary to treat larger tumors [18].
  • This case offers a practical strategy for the surgical management of this rare hand tumor [5].

Recurrence and Risk Factors

  • Giant cell tumors of the tendon sheaths in the hand are benign lesions where recurrence is the primary risk, typically occurring within 36 months of excision [2].
  • In total, 14.8% of patients had tumour recurrence in a systematic review of giant cell tumour of tendon sheath of the digits [11].
  • Type II tumours (two or more distinct tumours that were not joined together) were associated with higher recurrence rates than Type I tumours (single lesions) [11].
  • Well-designed studies combining the recurrence rates of several hand surgery centers implementing a standardized treatment are needed to better demonstrate the associated risk factors for recurrence [12].
  • Diffuse disease presents challenges due to high recurrence rates for tenosynovial giant cell tumors [7].
  • Our recurrence rate was 4,7% (n=3) in a study of 64 cases of giant cell tumor of tendon sheath [25].
  • In 3 patients (4,7%) bone erosion was found, and in 7 cases (10,9%) tendon involvement was found in a study of 64 cases of giant cell tumor of tendon sheath [25].
  • In the three recurrence cases, surgical excision was difficult [25].
  • We recommend selective use of curettage and cementing in Grade III lesions, particularly with extensive soft tissue involvement [35].

Complications

  • The pooled recurrence rate for giant cell tumour of tendon sheath of the digits after surgical excision is 14.8% [11].
  • Type II tumours (two or more distinct tumours that were not joined together) are associated with higher recurrence rates than Type I tumours [11].
  • Direct involvement of the extensor tendons, flexor tendons, or joint capsule places patients in a high-risk category for recurrence [21].
  • Total surgical excision ensuring removal of the attachment site (flexor sheath/palmar fascia) resulted in no local recurrences at a mean follow-up of 3.2 years for fibroma of tendon sheath [8].
  • En bloc resection and matched nonvascularized toe phalangeal transfer for Campanacci Grade 2 or 3 giant cell tumor of the phalanges resulted in no recurrences [17].
  • Patients with giant cell tumor of bone who are at higher risk of recurrence should be clinically followed more closely [15].
  • Metachronous multicentric giant cell tumor can recur with a disease-free interval of up to 24 years [43].

Recovery

  • Recurrence for giant cell tumors of the tendon sheaths in the hand typically occurs within 36 months of excision [2].
  • Surgical treatment for pigmented villonodular synovitis led to good functional results with an average Enneking score of 92% of normal limb function [10].
  • Well-designed studies combining the recurrence rates of several hand surgery centers implementing a standardized treatment are needed to better demonstrate the associated risk factors for recurrence in giant cell tumor of tendon sheath [12].
  • Patients with pigmented villonodular synovitis of the hip managed with arthroscopic synovectomy reported good functional outcomes without evidence of recurrence in a 19 patient cohort with an average follow-up of almost 7 years [76].

Key Evidence

  • [L4] In cases of infiltrative GCTTS, radiation therapy may provide local tumor control with preservation of hand function. [1] (10.1016/j.jhsa.2012.01.011)
  • [L4] Giant cell tumors of the tendon sheaths in the hand are benign lesions where recurrence is the primary risk, typically occurring within 36 months of excision. [2] (10.1016/j.otsr.2013.03.008)
  • [L4] Giant cell tumors of the synovial sheaths in the hand are benign lesions in which recurrence is the primary risk. [3] (10.1016/j.jhsa.2013.08.051)
  • [L4] Both curettage and resection/amputation are acceptable treatment options for the rare condition of giant cell tumour of bone in the hand, with a need to individualize treatment decisions based on the site and extent of disease to minimize treatment morbidity while maximizing disease control. [4] (10.1177/17531934211007820)
  • [Paper] This case offers a practical strategy for the surgical management of this rare hand tumor. [5] (10.1177/15589447261480384)
  • [L3] Intralesional excision remains a viable, and likely the standard, mode of treatment for most giant cell tumors of the distal radius unless there is extensive bone loss. [6] (10.1007/s11999-014-4054-3)
  • [L5] Complete surgical resection remains the treatment of choice for most patients with tenosynovial giant cell tumors, though diffuse disease presents challenges due to high recurrence rates. [7] (10.5435/jaaos-d-24-01255)
  • [L4] Total surgical excision ensuring removal of the attachment site (flexor sheath/palmar fascia) resulted in no local recurrences at a mean follow-up of 3.2 years. [8] (10.1177/1753193412469146)
  • [L4] Surgical treatment led to good functional results with an average Enneking score of 92% of normal limb function. [10] (10.1097/01.blo.0000224051.01873.fb)
  • [L1] [11] (10.1007/s11552-011-9341-9)
  • [L3] Well-designed studies combining the recurrence rates of several hand surgery centers implementing a standardized treatment are needed to better demonstrate the associated risk factors for recurrence. [12] (10.1186/s12891-019-2866-8)
  • [L4] This is a simple and effective modality of reconstruction after resection of distal radial tumors. [13] (10.1016/j.jhsa.2022.05.011)
  • [L4] Our observations suggest there are subsets of patients with giant cell tumor of bone who are at higher risk of recurrence and should be clinically followed more closely. [15] (10.1007/s11999-011-2172-8)
  • [L4] En bloc resection and matched nonvascularized toe phalangeal transfer resulted in a functional tumor-free digit with a low complication rate and no recurrences. [17] (10.1016/j.jhsa.2024.06.013)
  • [L3] Direct involvement of the extensor tendons, flexor tendons, or joint capsule puts patients in a high-risk category with respect to recurrence. [21] (10.1016/j.jhsa.2009.12.004)
  • [L4] [22] (10.2106/00004623-196951010-00005)
  • [L4] [23] (10.1007/s12593-010-0020-9)
  • [L3] The distal ulna may be widely resected with or without stabilization of the residual ulnar stump, yielding satisfactory local disease control and functional outcome. [24] (10.1177/1558944717743598)
  • [L4] [25] (10.11138/gchir/2013.34.5.149)
  • [Case_report] [26] (10.1016/j.jhsa.2014.11.010)
  • [L3] Based on data obtained from the number of studies available, intralesional excision appears to be more appropriate for the treatment of local lesions (eg, Grades 1 and 2) than Grade 3 GCTs of the distal radius. [27] (10.1007/s11999-012-2464-7)
  • [L4] We recommend selective use of this procedure in Grade III lesions, particularly with extensive soft tissue involvement. [35] (10.4103/0019-5413.77138)
  • [L4] Intralesional excision with cautery and methylmethacrylate provides a reliable method of treatment of giant cell tumors with good long-term functional results. [37] (10.1097/01.blo.0000128280.59965.e3)
  • [L4] Pigmented villonoid synovitis and giant-cell tumor of tendon sheath are benign synovial neoplasms with the potential for local recurrence. [38] (10.2106/00004623-198466010-00012)
  • [L4] This patient has the longest disease-free interval of a metachronous multicentric giant cell tumor reported to date, with 24 years passing between the initial presentation and the multicentric recurrence. [43] (10.1097/01.blo.0000068770.86536.e1)
  • [L3] [56] (10.1054/jhsb.2000.0522)
  • [Case_report] The use of a massive biocompatible bipolar unconstrained prosthesis is a viable treatment option for distal radius reconstruction after en-bloc resection of a giant cell tumour, offering rapid functional improvement without donor-site morbidity. [62] (10.1016/j.otsr.2013.04.001)
  • [L3] Intralesional excision with local adjuvant therapy is recommended for the treatment of giant cell tumor of bone because it results in a good functional outcome compared to extralesional excision. [63] (10.1007/s004020100317)
  • [L4] [65] (10.1177/17531934231222401)
  • [L3] Repeated curettage with adjuvants eventually resulted in the cure for all patients and is therefore a reasonable treatment for both primary and recurrent GCT of the small bones of the hands and feet. [68] (10.1302/0301-620x.95b6.30876)
  • [L4] Reconstruction after wide excision by nonvascularized fibular graft is a viable alternative for giant cell tumors of the lower end of radius though it is a challenging procedure and may be accompanied by major complications. [73] (10.1007/s00402-010-1059-6)
  • [L4] Patients reported good functional outcomes without evidence of recurrence in a 19 patient cohort with an average follow-up of almost 7 years. [76] (10.1177/2325967119s00413)
  • [L4] Although MRI findings and location might help in the diagnosis of a T-GCT, careful assessment is mandatory, especially in unusual locations. [84] (10.1186/s12891-016-1050-7)
  • [L4] Radiologists should be familiar with this imaging characteristic. [87] (10.1186/s12891-021-04610-0)
