Abstract

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.

(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.
