title: The use of lymphoscintigraphy in melanoma of the head and neck.
abstract: Lymphoscintigraphy has been shown to be of assistance in defining the lymphatic drainage pattern of melanoma. In this study, lymphoscintigraphy was performed on 25 patients with primary melanoma (stages I and II at diagnosis) of the head and neck to determine whether the lymphatic drainage seen on lymphoscintigram was the same as the surgeon's expected lymphatic drainage. The lymphoscintigrams were discordant in 21 of the patients (84 percent) with drainage to a lymphatic basin not predicted clinically. Based on the discordant lymphoscintigram, a change in surgical therapy occurred in 13 of 21 patients (62 percent). Of the 25 patients, 18 underwent prophylactic node dissections and 7 did not. Of the nodal basins removed, 27 of 38 nodal bases (71 percent) were seen on lymphoscintigraphy. Melanoma metastatic to lymph nodes was removed from nodal basins identified by the lymphoscintigram, but not predicted clinically, in two patients (8 percent). Historical anatomical patterns of lymph drainage and the clinical impression of experienced surgeons cannot reliably predict the pattern of lymphatic drainage in patients with melanoma of the head and neck.
