In some instances, it is mandatory to know the anatomy of the dorsal sensory branches of the ulnar nerve. The dorsal sensory branches consist of the area of most dense innervations with their anatomical variants. These variations are very important in the surgical and medical procedures dealing with the area. In this paper, we present a case of an unusual variation of the dorsal cutaneous ulnar nerve. The variation was observed in the operation of a right forearm of a 43 year old male following a traffic accident injury. Dorsal cutaneous Ulnar nerve was observed in an unusual course. It was piercing the flexor carpi ulnaris muscle’s tendon and then going into the skin superficially. To our knowledge, this type of variation has never been published before. The knowledge of this type of variation may be useful during surgeries and electrophysiological examinations of the area.
