Malignant giant cell tumor of tendon sheath

Malignant giant cell tumor of tendon sheath is an extremely rare malignant tumor, some cases have a poor outcome, the others, despite the histologically malignant features, have a good prognosis if wide surgical excision ablates the tumor completely. [Malignant giant cell tumor of the tendon sheaths in the hand Malignant giant cell tumor of the tendon sheaths and joints (malignant pigmented villonodular synovitis Giant cell tumor of tendon sheath is also named tenosynovial giant cell tumor. GCT of tendon sheath is a circumscribed tumor that does not always arise from the tendon sheath but may arise from the synovium. Most common in patients after 30 years old and it is the second most common benign hand tumor after a ganglion cyst These findings were consistent with a giant cell tumor of the tendon sheath. The recurrent tumor in December 1999 was a pseudoencapsulated nodular lesion with infiltration at the borders, and was mainly located in the subcutis with involvement of the dermis. Prominent cartilaginous tumor elements appeared in the center of the lesion (Fig. 3a)

A benign, but aggressive, giant cell tumor of tendon sheath developed over a period of 20 years into a metastasizing, histologically malignant giant cell tumor. Ultrastructure of the malignant tumor showed the same five cell types as described in giant cell tumors of tendon sheath A case of malignant giant cell tumor of the tendon sheath of the right hip, which developed in a 72-year-old Japanese woman, is described. The tumor exhibited histological similarities to a benign giant cell tumor of the tendon sheath (localized nodular tenosynovitis) In a patient with pigmented villonodular synovitis of the right knee joint, there occurred a malignant giant cell tumor of tendon sheath. There was clinical evidence of metastasis after the second local recurrence and the recurrent tumors were studied enzyme cytochemically and electron microscopically The pictured lesion is a tenosynovial giant cell tumor, localized type (also called giant cell tumor of tendon sheath). Although all the listed cell types can be seen in varying proportions within the tumor, the histiocytoid mononuclear cells are the neoplastic component and should always be present Giant cell tumors (GCTs) of the tendon sheath are the second most common tumors of the hand, with simple ganglion cysts being the most common. [ 1] Chassaignac first described these benign..

Giant Cell Tumor of Tendon Sheath, also known as pigmented villonodular tumor of the tendon sheath, is a benign nodular tumor that is found on the tendon sheath of the hands and feet. Diagnosis is made clinically with a firm, nodular mass that does not transilluminate with MRI studies showing decreased signal intensity on both T1-and T2. Giant cell tumor of tendon sheath is a rare, solitary benign soft tissue tumor which may arise in the tendon sheath tissues around the ankle and the toes of the foot. Most cases occur in the hand, where local recurrence after excision has been reported in up to 40% of cases. Approximately 3 - 10% of these tumors occur in the foot, most commonly. The malignant giant cell tumor of the tendon sheath is the 2nd most common tumor that affects the hands and fingers after ganglion cyst. This usually occurs in people between the ages of 30 and 50 years. It is associated with degenerative joint disease. Signs and Symptoms The patient may suffer from the following signs and symptoms.

Giant cell tumors of tendon sheath are usually small nodules between 0.5 and 3 cm in size. The uncommon localized intraarticular examples within the ankle, elbow, or hip may be larger. On gross examination, giant cell tumor of tendon sheath is a well-circumscribed, lobulated mass with a white, fibrous cut surface Polymerase chain reaction (PCR) assays have shown that giant cell tumors of the tendon sheath are polyclonal proliferations, [ 16] which suggests that these masses are nonneoplastic proliferations,..

Tenosynovial giant cell tumors are usually benign lesions that arise from the tendon sheath. It is unclear whether these lesions represent neoplasms or merely reactive masses. On imaging, these lesions are commonly demonstrated as localized, solitary, subcutaneous soft tissue nodules, with low T1 and T2 signal and moderate enhancement Giant cell tumor of tendon sheath (GCTTS) is a common tumor occurring on the tendon sheaths of the fingers. The nature of this lesion is still controversial: some researchers consider it a reactive process arising from chronic inflammation while others regard it as a tumor of presumed synovial cell or monocytic macrophage system origin Giant cell tumor of the tendon sheath (Figure 2): This is the second most common hand tumor.

A Giant Cell Tumor of Tendon Sheath (GCTTS) is a benign tumor consisting of many types of polygonal cells in a bed of collagen. It involves the joint fluid sac, tendon sheath, and synovial membrane of the joints. Synovial fluid is the lubricating fluid found in the joints (like knee, elbow), and synovium refers to the thin membrane that lines.

Giant cell tumor of the tendon sheath is a tumor, which affects mainly the hands of people aged 30 to 50 years with a female prevalence. Magnetic resonance imaging (MRI) is essential for diagnosis and treatment planning. The aim of this study is to evaluate the efficacy of multiecho gradient-echoes (MeGE) sequence in detecting hemosiderin which is the hallmark of this tumor Giant cell tumor of tendon sheath is the most common form of TSGCT. As the name implies, it arises from synovial-lined tendon sheaths. Giant cell tumor of tendon sheath occurs at any age, with peak incidence in the third to fourth decades. It usually presents as a painless, slowly growing mass Fibroma and giant cell tumor of the tendon sheath occur in similar patient populations and commonly are manifested as painless slow-growing masses in the peripheral extremities, particularly the hands, where they may interfere mechanically with tendon or joint function (, 30-, 32). Local excision is the treatment of choice for fibroma of the.

Recurrence is rare and there is no risk of malignant degeneration [2]. Other considerations in our case included a giant cell tumor of the tendon sheath and sarcoma, both of which would appear similar on exam and ultrasound to the fibroma of the tendon sheath. MRI can help with the diagnosis though biopsy is required for differentiation Giant cell tumor of tendon sheath (GCTTS) is a common soft tissue tumor.
