Axillary arch: a rare variation

ABSTRACT

The axillary arch is a muscle slip varying from7 to 10 cm in length and 5 to 15 mm inbreadth. It occasionally arises from the edge ofthe latissimus dorsi, at about the middle ofthe posterior fold of the axilla and crosses theaxilla in front of the axillary vessels and nervesto join the under-surface of the tendon of thepectoralis major, the coracobrachialis, or thefascia over the biceps. During the dissection ofa human cadaver, an unusual muscle band wasencountered and identified as an axillary archon the right side of a 60-year old male cadaver.The anomalous muscle band was an extensionfrom the lateral border of the latissimusdorsi muscle. The muscle measured 6 cm inlength, 2 cm wide and 2 mm thick. Since thismuscle may be the cause of different pathologies,we were prompted to discuss the clinicalrelevance of our findings (AU)
