Tenosynovial giant cell tumor
Introduction
Introduction to giant cell tumor of tendon sheath The lesion of giant cell tumor of the giant cell tumor (giantcelltumofofdondonsheath) is a solid, painless mass that occurs on the fingers and hands and is rare in the toes. Tumors can erode adjacent bones. basic knowledge The proportion of illness: 0.003% Susceptible people: more common in young people Mode of infection: non-infectious Complications: fibromatosis

Symptom
Symptoms of giant cell tumor of tendon sheath Common symptoms Slow growth of fingers and toes without pain...
The skin lesion of the giant cell tumor of the tendon sheath is a solid, painless mass, which grows slowly, usually less than 3 cm, and occurs in the fingers and hands. The toes are rare, and the young people are more common. In males, tumors can erode adjacent bones, and recurrence occurs after resection in about 25% of cases. Very rare malignant tendon sheath giant cell tumors have also been reported. Another tendon sheath tumor, fibroma of the tendon sheath, may be the subunit of tendon sheath giant cells. The type also invades the flexor tendon of the fingers and hands. The clinical morphology is the same as the giant cell tendon sheath tumor. The average age of onset is 30 years old, which is lighter than that of giant cell tenosynovoma.

Histopathology: This tumor is often lobulated. The lobule is surrounded by dense, transparent collagen. The intratumoral cells are composed of tissue-like mononuclear cells, osteoblast-like multinucleated giant cells, xanthomatous cells, chronic inflammatory cells, and hemosiderin. The phage and collagen matrix are mixed in different proportions. The other subtype of this tumor is called tendon sheath fibroma, which cannot be distinguished clinically. The tendon sheath fibroma has no phlephatic cells and hemosiderin macrophages, only occasionally A few multinucleated giant cells.
