Triggering of the flexor tendon at the wrist is a rare phenomenon. The triggering can be caused by many different conditions, including anomalous muscle, thickened synovium, rheumatoid disease and tumors. We report the case of a 34-year-old man with triggering at the wrist and carpal tunnel syndrome caused by a fibroma of the flexor tendon.

(A) The tumor associated with the flexor digitorum profundus tendon of 5th finger. (B) The nodule was connected with tendon sheath of flexor digitorum profundus of 5th finger. (C) A well-circumscribed, pale, lobulated, firm mass was excised. (D) Tenosynovectomy of flexor tendons because of tenosynovitis by irritation of tumor in carpal tunnel was performed.
