[Fourteen cases of malignant melanoma of the nasal cavity].
Fourteen cases of malignant melanoma of the nasal cavity were treated in our department during 31 years from 1962 to 1993. Ten were males and 4 were females. The ages ranged from 48 to 92 years old, with an average of 64.6 years. The chief complaints were epistaxis in 10 cases, nasal obstruction in 7, nasal cavity tumor in 1, and dull headache in 1. Histologically, 3 cases were amelanotic type, 3 oligomelanotic and 8 melanotic. The cellular types were classified as follows: 5 spindle and 9 large epitheloid cell types. Palliative treatment was performed in 1 patient, and 13 patients were treated radically. Local recurrences were seen in 8 patients, 9 regions; 3 near the posterior margin, 1 near the upper margin, 1 cheek, 2 ethmoid sinus, 1 maxillary sinus, and 1 uncertain. The cumulative survival rate among the 14 patients was 54.2% after 2 years and 31.0% after 5 years. One patient had local recurrence 13 years after surgical treatment.
