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

Abstract

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