A Case of Myoepithelial Carcinoma Originated from Inferior Turbinate / 대한이비인후과학회지

ABSTRACT

Myoepithelial carcinoma is a rare malignant tumor of the salivary glands with an incidence of less than 1%. Most cases arise in the parotid gland but have also been described in the submandibular gland and in the minor salivary glands. Myoepithelial carcinoma shows almost exclusively tumor cells with myoepithelial differentiation, although epithelial-myoepithelial carcinoma is characterized by a biphasic cell population represented by myoepithelial and ductal epithelial cells. Although myoepithelial carcinoma arising in the maxillary sinus has been reported, there is no report of myoepithelial carcinoma that has originated from inferior turbinate. We report, with a review of literature, a 72-year-old female patient diagnosed as myoepithelial carcinoma that has originated from the inferior turbinate of left nasal cavity.
