Malignant melanoma of the sinonasal mucosa is undoubtedly a rare and aggressive tumor, which affects patients over sixty years of age and is not associated with gender. Nasal obstruction and epistaxis are the most frequently reported symptoms, although the presentation is late and unspecific, which delays the diagnosis and worsens the prognosis. The traditional approach has been surgical treatment; radiotherapy has also been used; however its effectiveness remains uncertain. The purpose of the present study is to report two cases of malignant melanoma of the sinonasal mucosa and present a literature review.
