During routine dissection of an approximately 60-year-old female cadaver for the undergraduate medical students at Morphology Department of Federal University of Rio Grande do Norte, Brazil, was observed a variant branch originated from the second part of the axillary artery. The second part of the right axillary artery gave rise to aberrant brachial artery that travels down superficially in the medial aspect of the upper limb. Furthermore, this superficial brachial artery terminates in the superficial palmar arch completely replacing the ulnar artery at this level. Variations in the upper limb arterial distribution are notably important for surgeons performing interventional or diagnostic in vascular diseases.
