하비갑개의 상피-근상피 암종: 증례 보고.

Epithelial-myoepithelial carcinoma (EMC) is a rare and low-grade malignant salivary gland tumor including epithelial and myoepithelial components. EMC frequently arises in the parotid gland but infrequently originates from the salivary glands of the nasal cavity. Here, we report the case of an EMC arising from the inferior turbinate, one of the most uncommon sites. A 60-year-old female patient presented with left nasal obstruction for several months, and PNS CT showed an about 4×1.4-cm-sized heterogeneously enhancing polypoid mass originating from the inferior turbinate of the left nasal cavity. After surgical treatment, the patient was diagnosed with EMC based on pathologic examinations including histopathological and immunohistochemical tests. We report a case of a patient with EMC in the inferior turbinate who was observed over 18 months without radiation therapy after successful wide excision. [ABSTRACT FROM AUTHOR]
