The pectoralis major muscle is prone to various morphological incongruities. Variant muscular slips are common among them. However during routine dissection for undergraduate students in a 55-year-old male cadaver, a rare variation of the tendinous extension of the pectoralis major muscle was found. It was arising from the deep lamina of the muscular bilaminar tendon close to its insertion to the humerus. On its way to be attached to the medial intermuscular septum of the arm and finally to the medial epicondyle of the humerus, it crossed all the structures in the front of the arm from lateral to medial. Tracing this tendinous extension slip proximally, no separate muscular extension was observed. This variant slip may be named as pectoro-epicondylaris muscle. The knowledge of this particular variation could be of special interest to radiologists and clinicians in procedures such as muscle transformation, tendon transplantation and use of myo-cutaneous flaps during reconstructive surgeries
