Tendon sheath giant cell tumor resection

Giant cell tumor of the tendon sheath is a solid, painless mass with a slow growth, usually less than 3 cm. It occurs in the fingers and hands, and is rare in the toes. Young people are more common than females. Tumors can erode adjacent bones. About 25% of cases relapse after resection, and extremely rare malignant giant cell tumors of the tendon sheath have also been reported. Another fibroma of the tendon sheath may be a subtype of the giant cell of the tendon sheath and invades the flexor tendon of the fingers and hands. The clinical form is the same as that of giant cell tendon sheath tumors. The average age of onset is 30 years. Tendon sheath tumors are young.
