Tenosynovial Giant Cell Tumor in the knee: Case report

Abstract

Tenosynovial Giant Cell Tumors (GCTT) are benign proliferative neoplasms of undetermined etiology. Unlike bone tumors, their growth is usually slower, originating from the synovial tissue of tendon sheaths, joints, bursae, and fibrous tissues adjacent to tendons, usually in the appendicular skeleton. GCT corresponds to less than 2% of all soft tissue tumors and its most common location is on the hands, corresponding to 80-85% of cases. In large joints, its incidence reaches 10%, and can reach large dimensions. The least commonly affected sites are the knee and ankle. This report presents a rare case of TTCG located in the knee, without bone involvement, whose treatment was tumor resection using the arthroscopic method.
