Giant cell tumors of synovial sheaths of tendons develop from synovial joint and periarticular joints. These tumors constitute a benign proliferative disorder of the synovium whose etiopathogenesis is still undetermined. We report the case of a 45-year-old patient. Which presents a voluminous tumor at the expense of the fourth finger of the right hand evolving since twelve months. It is a large mass of 6 centimeters of the large diameter opposite the plamary face of the two proximal phalanges of finger. The diagnosis of a giant cell tumor was previously confirmed by a biopsy. The patient was operated under locoregional anesthesia, with a pneumatic tourniquet at the root of the limb. Dissection was meticulous because the tumor was in contact with the digital pedicles thinned. The tumor was resected extracapsularly. At 9 months follow-up, there was no local recurrence, but the patient maintained a flexion deficit of the proximal interphalangeal joint estimated at 40 degrees.
