Abstract

Myoepithelioma is a rare benign tumor, most frequently located in the salivary gland. However, involvement of an extra-salivary gland is even rarer and very few cases involving the nasal cavity have been reported in the literature. A 51-year-old female patient presented with a complaint of progressive nasal obstruction and occurrence of recurrent epistaxis in the left nasal cavity over several months. A hemorrhagic and erythematous mass occupying the left nasal cavity was observed on physical examination using a nasal endoscope. A preoperative angiogram confirmed that he tumor was receiving blood supply from the sphenopalatine artery. We performed embolization to prevent hemorrhage during surgery; one day later, the lesion was successfully removed through endoscopic excision. Histopathological examination revealed that the tumor contained myoepithelial cells and myxoid stroma. Immunohistochemical studies showed that the tumor was positive for cytokeratin marker and S-100 protein, confirming the diagnosis of myoepithelioma. The patient recovered without any nasal symptoms or postoperative deficits.
