In rare cases, lymphatic drainage from the malignant melanomas in the upper extremity may follow an unpredictable pattern (outside the axillary nodes), and these aberrant sentinel nodes may represent the only site of regional lymph node metastases. The precise anatomical landmarks and technical aspects of surgical exploration of these aberrant sentinel lymph nodes are rarely described in the literature, including aberrant sentinel mid-humeral lymph nodes. This report describes a step-by-step dissection of the mid-humeral sentinel lymph nodes in two patients with a primary malignant melanoma in the upper extremity, identified by lymphatic mapping. Recognition of precise regional anatomy and following a special surgical technique makes the procedure safe and successful, thus avoiding local complications and allowing a prompt recovery.
