Sentinel node (SN) biopsy has become standard in staging of cutaneous melanoma. As skin lymphatic drainage is complex, preoperative empirical assessment of SN localization is virtually impossible. Therefore in order to identify all regional lymphatic basins corresponding to a specific primary tumor is mandatory to carry out preoperative lymphoscintigraphy. In this paper we present a clinical case that highlights the importance of identifying, biopsy and histological analysis of all SN in order to achieve a correct staging of the patient, followed by appropriate treatment according to the real clinical stage of the disease.
