Overview¶

• The diagnosis and treatment of suspected hand neoplasms should proceed in an orderly fashion similar to accepted methods applied to tumors in other locations of the extremities [1].
• Giant cell tumors of the tendon sheaths in the hand are benign lesions where recurrence is the primary risk [3, 4].
• Recurrence of giant cell tumors of the tendon sheaths typically occurs within 36 months of excision [3].
• The fundamental consideration in the management of hand tumours is to reconcile adequate tumour clearance with the maintenance of function and appearance [20].
• Complete surgical resection remains the treatment of choice for most patients with tenosynovial giant cell tumors [15].
• Diffuse tenosynovial giant cell tumor disease presents challenges due to high recurrence rates [15].
• Curettage, cryosurgery, and cementation performed by experienced surgeons appears to be a safe, effective, and reliable method for treating selected giant cell tumors of the hand [5].
• In cases of infiltrative giant cell tumor of the tendon sheath, radiation therapy may provide local tumor control with preservation of hand function [12].
• En bloc resection of the tumour and reconstruction with a fibular graft where necessary should be considered as the treatment of choice in giant cell tumour of the hand [10].
• En bloc resection of the tumour and reconstruction with an autograft should be considered in the treatment of recurrent giant cell tumour of the hand [8].
• En bloc resection and matched nonvascularized toe phalangeal transfer for Campanacci Grade 2 or 3 giant cell tumor of the phalanges resulted in a functional tumor-free digit with a low complication rate and no recurrences [35].
• 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 [28].

Anatomy & Pathophysiology¶

Clinical Presentation and Demographics¶

• Giant cell tumour of tendon sheath (GCTTS) is the second most common benign proliferative tumour in the upper extremities after ganglion cysts [102].
• GCTTS are usually slow-growing, painless, benign soft tissue tumours [102].
• GCTTS are most commonly found in the fingers and among women in their fourth and fifth decades [102].
• The male-to-female ratio for GCTTS of the digits is 1:1.47 [23].
• The mean age range for GCTTS of the digits is 32 to 51 years [23].
• Pain was reported in 15.7% of GCTTS cases and sensory disturbances in 4.57% of cases [23].
• A definite history of trauma was recorded in 5% of GCTTS lesions [23].
• The most frequent tumour location for GCTTS of the digits is the index finger (29.7%) [23].
• In a series of 64 cases, the most frequent location for GCTTS was the long finger (23.5%), followed by the thumb, index finger, and hand (20.3% each) [49].
• Patients with GCTTS arising in the fingers complained of a painless mass in almost every instance [24].
• The duration of symptoms for finger GCTTS ranged from two weeks to fifteen years, with an average duration of thirty-eight months [24].
• GCTTS are usually firm, lobulated, and non-tender masses [24].
• As the tumour grows, patients may present with swelling, pain, and limitation of movement [102].

Anatomical Distribution and Morphology¶

• Fifty-three xanthomas (GCTTS) arose adjacent to joints in the fingers, whereas twenty-nine bore no relation to joints [24].
• Thirty-one of ninety-one finger GCTTS occurred at the distal joints [24].
• Of the thirty-one distal joint GCTTS, eighteen were on the dorsal aspect and thirteen were distributed evenly on the radial, ulnar, and volar aspects [24].
• Type I GCTTS (single lesions) were more frequently detected (78.7%) than Type II tumours (two or more distinct tumours that were not joined together) (21.3%) [23].
• Type 1 GCTTS includes a nodular or multinodular lesion surrounded by a capsule, while Type 2 describes tumours with no connective tissue membrane and satellite, diffuse, or multicentric nodules [102].
• The average size of GCTTS was 1.35 cm, with a range of 0.3 cm to 5 cm [49].
• Bone erosion was found in 3 patients (4.7%) in a series of 64 GCTTS cases [49].
• Tendon involvement with flexors/extensors ratio of 4:3 was found in 7 cases (10.9%) in a series of 64 GCTTS cases [49].
• Involvement of the neurovascular bundle was presented in 7 patients (10.9%) in a series of 64 GCTTS cases [49].
• A case report describes the first patient with three separate GCTTS developing from both flexor and extensor tendons in a single digit [7].

Histology and Pathogenesis¶

• Microscopically, all GCTTS contained multinucleated giant cells, histiocytes, and haemosiderin deposits [49].
• GCTTS originates from the synovial membrane, tendon sheath, or synovial bursa [102].
• Inflammation resulting from reactive or regenerative hyperplasia is the generally accepted theory of pathogenesis for GCTTS [102].
• Genetic factors have been observed in previous studies regarding GCTTS pathogenesis [102].
• Fibroma of tendon sheath is histologically distinct from giant cell tumor of tendon sheath, a lesion with which it is commonly confused [16].

Diagnostic Imaging¶

• Radiography can be helpful in evaluating cortical destruction but is not helpful in the definitive diagnosis of GCTTS [102].
• Magnetic resonance imaging (MRI) is the most useful examination for the diagnosis and treatment planning of GCTTS [102].
• Al-Qattan classified GCTTS with MRI into two types according to the risk of recurrence [102].

Classification¶

• Giant cell tumors of the synovial sheaths in the hand are benign lesions in which recurrence is the primary risk [4].
• Recurrence for giant cell tumors of the tendon sheaths typically occurs within 36 months of excision [3].
• The Al-Qattan classification divides giant cell tumours of tendon sheath into two main types based on whether the entire tumour is surrounded by one pseudocapsule as assessed by the surgeon during surgery [90].
• Type I tumours are defined as those where the entire tumour is surrounded by one pseudocapsule [90].
• Type II tumours are defined as those where the entire tumour is not surrounded by one pseudocapsule [90].
• Type I tumours are sub-classified according to the thickness of the capsule, lobulation of the tumour, the presence of satellite lesions, and the diffuse or multicenteric nature of the tumour [90].
• Type II tumours are sub-classified according to the thickness of the capsule, lobulation of the tumour, the presence of satellite lesions, and the diffuse or multicenteric nature of the tumour [90].
• In a prospective study of 43 consecutive cases, none of the type I tumours (n=30) recurred [90].
• In a prospective study of 43 consecutive cases, recurrence occurred in five out of 13 type II tumours [90].
• Second recurrences were seen with type II B and C tumours, but not type II A tumours [90].
• 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%) in a systematic review of 605 patients [23].
• Type II tumours were associated with higher recurrence rates compared to Type I tumours in a systematic review of 605 patients [23].
• Direct involvement of the extensor tendons, flexor tendons, or joint capsule puts patients in a high-risk category with respect to recurrence [43].
• Preoperative diagnosis and meticulous surgical technique were found to be the only predictive factor of recurrence in a series of 14 cases [34].
• The overall recurrence rate in a systematic review of 605 patients was 14.8% [23].

• The tumors were usually firm, lobulated, and non-tender [24].
• Fifty-three xanthomas arose adjacent to joints in the fingers, whereas twenty-nine bore no relation to joints [24].
• Thirty-one of the ninety-one tumors in the fingers occurred at the distal joints [24].
• Eighteen of the thirty-one distal joint tumors were on the dorsal aspect of the joint, and thirteen were distributed about evenly on the radial, ulnar, and volar aspects of the joint [24].
• The most frequent tumour location for giant cell tumour of tendon sheath of the digits was the index finger (29.7%) [23].
• Pain was reported in 15.7% of cases and sensory disturbances in 4.57% of cases [23].
• A definite history of trauma was recorded in 5% of lesions [23].
• 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%) [23].
• The male-to-female ratio for giant cell tumour of tendon sheath of the digits was 1:1.47 [23].
• The mean age for giant cell tumour of tendon sheath of the digits ranged from 32 to 51 years [23].
• A tendon tumour can present as a trigger finger [18].
• Trigger wrist caused by a giant cell tumour of tendon sheath has been reported [26].
• The trigger phenomenon in trigger wrist caused by a giant cell tumour of tendon sheath probably occurred when the tumour entered and left the distal carpal tunnel [26].
• Fibroma of tendon sheath is a benign soft tissue tumor that has a predilection for the hand [16].
• Fibroma of tendon sheath may be more common than has been previously recognized [16].
• The differential diagnosis of a soft tissue tumor in the digits and hand is usually limited to a ganglion, an inclusion cyst, or a giant cell tumor of tendon sheath (xanthofibroma) [16].
• Fibroma of tendon sheath should be included in the differential diagnosis of a soft tissue tumor in the digits and hand [16].
• A case of fibroma of tendon sheath presented as a 6-year history of a slowly enlarging palmar mass of the left index finger [16].

• Flexion of the digit was limited by the bulge in a case of fibroma of tendon sheath [16].
• The unusual location of a fibroma of the tendon sheath and atypical nature of the triggering phenomenon can lead to it being reported as a rare cause of median nerve compression at the wrist [50].
• Giant cell tumor of tendon sheath and pigmented villonodular synovitis are benign, locally invasive tumors involving synovium, tendon sheaths, and bursae [47].
• Patients with giant cell tumor of tendon sheath or pigmented villonodular synovitis may present with a discrete mass or with joint swelling, pain, or locking or catching [47].
• The knee and digits of the hand are the most common locations of lesions for giant cell tumor of tendon sheath and pigmented villonodular synovitis [47].
• Multifocal lesions of giant cell tumor of tendon sheath and pigmented villonodular synovitis are rare [47].
• The authors report the uniqueness of a case of multicentric giant cell tumor in the upper extremity [9].

• A 65-year-old man presented with a slowly enlarging mass on the dorsal aspect of the left thumb consistent with a recurrent giant cell tumor of the tendon sheath [33].

Investigations¶

• The differential diagnosis of a soft tissue tumor in the digits and hand is usually limited to a ganglion, an inclusion cyst, or a giant cell tumor of tendon sheath [16].
• Fibroma of tendon sheath should be included in the differential diagnosis as it may be more common than has been previously recognized [16].
• Fibro-osseous pseudotumor of the digit should be considered in the differential diagnosis of rapidly enlarging digital lesions [64].
• Although MRI findings and location might help in the diagnosis of tenosynovial giant cell tumors, careful assessment is mandatory, especially in unusual locations [129].

Treatment¶

General Principles¶

Surgical Excision¶

• 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 [15].
• En bloc resection of metacarpal giant cell tumors with reconstruction by iliac graft appears to be an effective treatment [14].
• 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 [35].
• 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 [11].
• Local excision of the tumour appears to be a satisfactory method of treatment for Nora’s lesion [109].
• Preoperative planning aided by a tissue diagnosis with fine needle aspiration cytology, wide surgical exposure, and meticulous dissection with help of magnification are imperative for a successful outcome in giant cell tumor of tendon sheath [34].
• In all cases of giant cell tumor of tendon sheath, magnifying loupe or operating microscope was used during surgical excision [49].
• In cases of infiltrative giant cell tumor of tendon sheath, radiation therapy may provide local tumor control with preservation of hand function [12].

Recurrence and Adjuvant Therapy¶

• 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 [3].
• In a study of 64 cases of giant cell tumor of tendon sheath, the recurrence rate was 4.7% (n=3) [49].
• In a systematic review of 605 patients with giant cell tumor of tendon sheath of the digits, 14.8% of patients had tumour recurrence [23].
• Repeated curettage with adjuvants eventually resulted in the cure for all patients and is therefore a reasonable treatment for both primary and recurrent giant cell tumor of the small bones of the hands and feet [105].
• Intralesional excision with cautery and methylmethacrylate provides a reliable method of treatment of giant cell tumors with good long-term functional results [71].
• 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 [98].
• 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 [29].
• 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 giant cell tumors of the distal radius [52].
• 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 [28].

Reconstruction and Resection Options¶

• 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 [6].
• Aggressive and malignant bone tumors of the second through fifth metacarpals generally require en bloc bone excision [17].
• Ray excision is usually best for lesions of the second and fifth metacarpals [17].
• If bone graft has been used for reconstruction, carpometacarpal arthrodesis and MCP ligament reconstruction or silicone arthroplasty may be practical [17].
• Whatever level is chosen for reconstruction, it is essential that an adequate, safe margin of normal tissue first be excised en bloc with the tumor [17].
• Aggressive tumors of the second through fifth metacarpals that have invaded soft tissue or sustained pathologic fractures often require excision of not only the involved ray but also the contiguous ray or rays radial and ulnar to the involved digit [17].
• 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 [17].
• Retention of a sensate and relatively mobile thumb may be considerably more esthetic and functionally satisfactory than a forearm- or wrist-level amputation [17].
• 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 [17].
• Malignant soft tissue tumors in the palm or carpal tunnel often require at least partial hand amputation [17].
• If treated by only local or limited excision, the chance of recurrence is extremely high particularly in the setting of a positive margin for malignant soft tissue tumors in the palm or carpal tunnel [17].
• Below-elbow amputation is necessary to treat larger tumors of the palm or carpal tunnel [17].
• Wide en bloc excision of soft tissue sarcomas with negative margins is required to achieve local control of the lesion [17].
• At a minimum, aggressive soft tissue tumors, such as bone tumors, require ray resection or removal of multiple rays [17].
• 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 [17].
• 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 [17].
• 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 [68].
• 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 [111].
• En bloc resection is recommended for aggressive giant cell tumours (GCT) of the bone involving the distal end of the radius to minimize the risk of recurrence [91].
• The distal ulna may be widely resected with or without stabilization of the residual ulnar stump, yielding satisfactory local disease control and functional outcome [48].
• This is a simple and effective modality of reconstruction after resection of distal radial tumors using centralization of the ulna [30].

Complications¶

• Recurrence is the primary risk associated with giant cell tumors of the tendon sheaths in the hand [3].
• The overall recurrence rate for giant cell tumour of tendon sheath of the digits is 14.8% [23].
• Type II tumours (two or more distinct tumours that were not joined together) are associated with a higher risk of recurrence compared to Type I tumours [23].
• Direct involvement of the extensor tendons, flexor tendons, or joint capsule places patients in a high-risk category for recurrence [43].
• Surgical treatment of pigmented villonodular synovitis led to good functional results with an average Enneking score of 92% of normal limb function [32].
• A tendon tumour arising from the superficialis tendon can present as a trigger finger [18].
• A giant cell tumour of the tendon sheath can cause a trigger wrist phenomenon when the tumour enters and leaves the distal carpal tunnel [26].
• A fibroma of the tendon sheath in an unusual location can cause a triggering phenomenon and median nerve compression at the wrist [50].
• Total surgical excision ensuring removal of the attachment site (flexor sheath/palmar fascia) for fibroma of tendon sheath resulted in no local recurrences at a mean follow-up of 3.2 years [11].
• Patients with giant cell tumor of bone in the hand who are at higher risk of recurrence should be clinically followed more closely [41].
• Both curettage and resection/amputation are acceptable treatment options for 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 [6].
• Below-elbow amputation is necessary to treat larger malignant soft tissue tumors in the palm or carpal tunnel [17].
• Patients who received preoperative radiotherapy for hand tumors had a decrease in functional outcomes and grip strength that averaged 66% compared with the contralateral hand [55].
• None of the patients who underwent single-ray amputation for tumors of the hand, including giant cell tumors of bone, had local recurrences [55].
• A 29-year-old patient with recurrent giant-cell tumor of the digit was treated by phalangeal excision and toe phalanx transplant [54].

Recovery¶

• Recurrence of giant cell tumors of the tendon sheaths in the hand typically occurs within 36 months of excision [3].
• 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 [11].
• In cases of infiltrative GCTTS, radiation therapy may provide local tumor control with preservation of hand function [12].
• At 2-year final follow-up examination, no recurrence was noted, finger range of motion was full, and the x-ray film contour of the phalanx had returned to normal [13].
• Surgical treatment led to good functional results with an average Enneking score of 92% of normal limb function [32].
• En bloc resection and matched nonvascularized toe phalangeal transfer resulted in a functional tumor-free digit with a low complication rate and no recurrences [35].
