Mucosal melanoma (MM) in the head and neck (H&N) is relatively rare and behaves in distinct pattern from cutaneous melanoma (CM). We performed this study to define clinical characteristics and outcomes of patients and emphasize MM differences from CM. Forty-one patients with MM located in H&N were assessed. 94 CM patients originated from H&N region were also used for comparison. Patients had oral cavity (51%) and sinonasal location (49%).The median age was 60 years and gender distribution was equal. Thirty-two (78%) patients had localized stage, four (10%) patients had regional lymph node metastasis, and five (12%) patients had distant metastasis. The 1- and 5-year overall survival rates were 81% and 58%, respectively. Outcomes were similar between sinonasal and oral cavity patients ( P  = 0.67). Advanced disease was the significant prognostic factor for outcome ( P  = 0.03). MM patients are older ( P  = 0.008) and more diagnosed as a localized disease patients at presentation than those with CM ( P  = 0.06). Overall survival rates were identical in patients with MM and CM ( P  = 0.53). In conclusion, despite different clinical features, outcome was identical in patients with MM and CM located in the H&N region.
