The extensor digitorum brevis manus is a supernumerary muscle of the dorsum of hand and is a relatively rare finding during dissection. Only 2-3% of the cases are found world wide. Here we report the case of extensor digitorum brevis manus in an approximately 65-year-old Indian male cadaver. This report discusses the variant anatomy, morphology, review of literature and clinical implications of this muscle. We believe that it is of importance to report the observation of this muscle as the variation reported herein should be of interest to clinicians, surgeons and anatomists for academic purposes.
