Unusual sentinel lymph nodes detected by lymphoscintigraphy in cutaneous melanoma patients [Linfonodi sentinella "inusuali" alla linfoscintigrafia in pazienti con melanoma cutaneo]

Lymphoscintigraphy and radio-guided research of the sentinel lymph node is the most important investigation in the staging of patients with cutaneous melanoma, because it allows the identification of the lymphatic drainage pathways, not always predictable, and locate the sentinel node in classic basins and in "unexpected" regions. The aim of this study was to evaluate the incidence of cases of unusual sentinel nodes detected by lymphoscintigraphy and their prognostic significance in patients with cutaneous melanoma.
