Palmaris longus (PL) is a muscle of the forearm that is known for its many anatomical variants in the human body. Though the action of PL is frivolous, it is of significance to the surgical practice of both plastic and hand surgeons. In the current case we report the findings of a duplicated Palmaris longus which was partially fused, and also the presence of an Accessory abductor digiti minimi (AADM) muscle that arises from the duplicated segment of Palmaris longus. In the current report, we explain the course of the above muscles and their effects on the surrounding vital nerves and vessels. Clinical knowledge of such anatomical variants could help facilitate the approach to a patient with hand problems and address the use of PL graft for reconstructive hand surgeries.
