Abstract

Axillary arch muscle is a variant muscular structure of the axilla which is described as Langer’s muscle, axillary arch or muscular axillary arch by different authors. During the routine dissection of the left axillary region we found a muscular slip which originated from the anterior border of the latissimus dorsi muscle and got inserted on the under surface of the tendon of pectoralis major muscle. Arterial, venous and nervous structures passed under this muscular slip. This has been observed for the first time in the last 20 years in which around 200 cadavers were dissected in this institute. Although axillary arch is not very rare, it is generally neglected and not explored or described well. It has immense clinical and morphologic importance for surgical operations performed on axillary region; thus, surgeons should well be aware of its possible existence.[1]
