Tenosynovial giant cell tumor (TSGCT) is a benign, slow‐growing solid soft tissue tumor that arises from the tenosynovium of a tendon sheath or the synovium of a diarthrodial joint. TSGCT accounts for 1.6% of all soft tissue tumors and typically arises in the limbs, with the most common location being the hand, whereas occurrence in the foot is rare. Local complete resection of the lesion is an effective treatment for TSGCT. However, if left untreated, the tumor can lead to persistent pain, limited movement, joint destruction, and osteoarthritis. We present the case of a young gentleman diagnosed with a TSGCT of the forefoot, a rare but locally aggressive lesion that was successfully treated with complete excision.
