A case of myoepithelioma of the nasal cavity.
Myoepithelioma is a rare tumor, most frequently located in the salivary gland. Case reports of extra-salivary myoepithelioma are sporadic, with only one case in the nasal cavity. A 68-year-old male patient presented with a myoepithelioma of the nasal cavity manifesting as nasal obstruction and epistaxis, which was treated successfully with endoscopic excision. Histological examination revealed myoepithelial cells and myxoid stroma, which confirmed the diagnosis of myoepithelioma. The behavioral pattern is similar to if not identical with that of the mixed tumor, pleomorphic adenoma, which is benign, but the potential for recurrence is always present, especially if complete resection is not achieved.
