Introduction The axillary arch, also known as Langer’s muscle or the axillopectoral muscle is a rare muscular anomaly of the axilla. It is described as a thin muscular slip extending usually from the latissimus dorsi to the pectoralis major.Case Report During routine dissection classes for undergraduate students in the Department of Anatomy, Kasturba Medical College, Manipal, an anomalous axillary arch was observed in the left upper extremity of a 55-year- old male cadaver.Muscular slips arising from the lateral edge of the latissimus dorsi muscle were blending with the deep fascia covering the pectoralis major muscle and the deep fascia of the arm. Interestingly the upper and lower fibers of the muscle exhibited a twisted pattern and were much bulkier unlike the cases reported so far.Discussion & Conclusion Although the existence of the axillary arch is not very rare, it is generally neglected and not explored or described well. It has immense morphological and clinical importance in axillary surgeries, axillary vein entrapment syndrome, neurovascular complaints of the upper limb etc.
