Abstract

Unlike its cutaneous counterpart, prognostic markers for primary mucosal malignant melanoma have not been well elucidated. It has been recently demonstrated that microvascular density (MVD) in cutaneous malignant melanoma has a significant negative correlation with survival; however, this has not been well-studied in mucosal malignant melanoma of the head and neck. This study explores the potential association between MVD, various histological parameters, and the outcome of a series of sinonasal and oral mucosal melanomas. Nineteen such cases were immunostained with CD31 and the MVD was calculated by using Bioquant Image Analysis Software (R and M Biometrics, Nashville, TN). These cases included 16 sinonasal and 3 oral cavity tumors. The 1,2,3,4 and 5 years overall survival rates were 75,57, 61,46 and 46%,respectively. The MVD of the tumors ranged from 25.7 to 732 vessels/mm 2 (mean 142.8 vessels/mm 2; median 84.7 vessels/mm 2). There was no significant correlation between the MVD and the different clinicopathological features seen within the tumors. There was also no correlation between the MVD and relapse free and overall survival. The results of this study suggest that MVD does not correlate with outcome in mucosal melanoma of the head and neck as seen in cutaneous melanomas. Further larger studies are needed to identify predictive and prognostic markers in such melanomas.
