A case of an unusual variation of the blood supply of an upper limb is presented.

It ran under the lower border of the teres major muscle instead of passing through the lateral axillary foramen, then followed its usual course around the surgical neck of the humerus, supplying the deltoid muscle. It was also found that instead of arising from the brachial artery, the deep brachial artery arose from the posterior circumflex humeral artery. Variations are reported and their clinical relevance is discussed.
