Lymphoscintigrams demonstrated sentinel nodes in nonpredicted (discordant) sites in 114 of 362 head and neck melanoma patients (31.5%). Seven of 51 patients with regional node metastases (13.7%) had involvement in a discordant site. It is concluded that all sentinel nodes should be removed and examined to obtain reliable prognostic information.
