Abstract:
A 27-year old man had a swelling over the back of his right hand that was painful on exertion. Operative revision revealed an extensor indicis brevis muscle. The frequency of this variant at autopsies is markedly below one percent; in addition to true neoplasms, the differential diagnosis includes ganglion cysts and synovialitis of the extensors.
