The giant cell tumor of tendon sheath (GCTTS) is a benign lesion most commonly attached to the tendons and bones of the fingers, hands, and wrists. The involvement of GCTTS to the foot is uncommon. The GCTTS invading tarsal bones and intertarsal joints is not described yet, and the appropriate diagnosis and treatment remain unclear. We report a case of GCTTS with the involvement of tarsal bones and intertarsal joint. Computed tomography scan and magnetic resonance imaging were used to further diagnose and evaluate the quality and range of tumor. The patient was treated with surgical excision of the tumor without application of bone graft. After adequate clearance of the tumor, the patient returned to an asymptomatic walk in 3 months. No malfunction, fracture, or tumor recurrence was found in 2-years follow-up. This report includes clinical, radiologic, histologic diagnostic, and surgical challenges in an unexpected lesion and a review of the literature.
