Tenosynovial Giant Cell Tumor of the Ankle: A Case Report with an Unusual Location

Abstract

Tenosynovial giant cell tumor (TSGCT), is a slow-growing benign tumor that originates from the tendon sheath or bursae. TSGCT of the foot and ankle has been reported much less frequently compared to the reported cases in hand and knee. Morphologically it is classified as the localized form which often seen in the hand and the diffuse form seen in large joints. TSGCT should be considered in the differential diagnosis of soft tissue tumors of the foot and ankle. Clinical and radiological findings of intra-articular localized form of TSGCT in the ankle were presented in this study.
