Abstract
We reviewed the clinical data of 18 patients with mucosal malignant melanoma of the nasal/paranasal cavity at our hospital between 2007 and 2016. There were 6 men and 12 women, aged 55-84 years （median: 72）. The clinical TNM classification according to the 7th AJCC/UICC was as follows: T3, 10 cases; T4a, 8 cases; N0, 17 cases; N1, 1 case; M1, 2 cases; Stage Ⅲ, 10 cases; Stage Ⅳa, 6 cases; Stage Ⅳc, 2 cases. The 3-year local control rate （Kaplan-Meier method） was 67％ and the overall survival rate was 80％. The rate of local recurrence was 70％ for patients with complete resection and the rate of recurrence due to skin lesion was 86％. The rate of recurrence of malignant melanoma was very high, thus the extent of resection must be considered case by case.
