Coincidence of superficial brachiomedian artery and bitendinous palmaris longus: a case report.

We present a unique unilateral case of a superficial brachiomedian artery that coincides with a variable palmaris longus muscle in a male cadaver. The superficial brachiomedian artery branched at the distal part of the right arm and coursed superficially in the cubital and antebrachial regions. Then it passed through the carpal canal and formed a complete superficial palmar arch by joining the trunk of the ulnar artery.
