Melanoma Presenting as a Maxillary Sinus Mass: A Case Report

Maxillary sinus melanoma is a rare mucosal melanoma difficult to
diagnose in the absence of pigmentation. Intranasal masses presenting
with the features of occult malignancy and rapid progression should
always be investigated in the line of melanoma irrespective of
pigmentation. The histopathological and immunohistochemical examination
helps to confirm the diagnosis.
