Intratendinous Ganglion in the Extensor Digitorum Communis of the Hand: A Case Report

Ganglions are most common benign lesion of the hand and wrist. Although they usually arise from tendon sheaths, those originating within a tendon substance itself are rare. The etiology, pathogenesis and treatment of the intratendonous ganglion are not completely understood. We report a case of an intratendinous ganglion that developed in the extensor digitorum communis tendon of the hand and caused the extension limitation of the wrist. Treatments consisted of the intratendinous ganglion excision and meticulous tendon repair followed by tenosynovectomy.

Clinical Experience of Intratendinous Ganglion in the Extensor Tendon of Hand

Ganglion is the most common soft tissue tumor of the hand, and most of them usually arise from the scapholunate ligament, scarphotrapezial ligament, radiocarpal joint or flexor tendon sheath. However, intratendinous ganglion is very rare with unknown etiology and pathogenesis that originates within tendon. We have experienced three clinical cases of intratendinous ganglion in extensor tendons of hand. The average of patients at operation was 36 years. All patients were treated by excision of the ganglion in conjunction with tenosynovectomy followed by repair of the tendon. The length of mean follow up time was 6.7 months and all of them showed no evidence of recurrence.
