This study documents a case of an epithelial-myoepithelial carcinoma (EMC) in the left nasal cavity. A 70-year-old woman who presented with recurrent epistaxis of the left nasal nostril of 3 months duration was found to have a polypoid tumor in the left nasal cavity. A computed tomography (CT) scan revealed a tumor to occupy the left inferior and middle nasal cavity which had destroyed the inferior nasal turbinate, and a horizontal scan showed the tumor to occupy the middle and posterior nasal cavity. Since the tumor was connected to the lateral wall of the left nasal cavity with a narrow stalk, the tumor was excised by peeling the mucosa from the wall of the left nasal cavity. Based on the histological and immunohistochemical findings, the tumor was diagnosed to be an EMC. The follow-up at 12 months after the operation showed no evidence of recurrence.
