title: Mucosal malignant melanoma of the nasal cavity.
abstract: Mucosal malignant melanoma (MMM) of the nose is extremely rare. We report a case of MMM of the nasal cavity in a 60-year-old male patient presenting with a polypoidal mass in the right nasal cavity. It was increasing gradually and obstructing breathing. A biopsy of the lesion was done with a clinical suspicion of inverted papilloma/carcinoma. Microscopy revealed features suggestive of malignant melanoma with minimal melanin pigmentation. Subsequently wide local excision was done. Diagnosis of malignant melanoma was facilitated by histochemistry and immunohistochemistry.
