Benign Giant Cell Tumor of the Foot Originating from Talonavicular Joint

Benign Giant Cell Tumor is a relatively common benign lesion which usually appears as an enlarging painless mass and has a synovial origin. Although benign giant cell tumors generally involve tendon sheaths, they are infrequently documented in the foot. A 45 years old female presented with a complaint of a lump on the top of her left foot. Under general anesthesia with a pneumatic tourtniquet the mass excised with great care not to leave any residual tumor tissue that can cause recurrence. Benign giant cell tumor of the foot can be associated with talonavicular joint capsule which can be detected with MRI imaging and total excision of the lesion is mandatory to prevent recurrence.
