ABSTRACT
Malignant carcinoma involving the sinonasal cavity is a rare tumor that is usually diagnosed as squamous cell carcinoma. Mucoepidermoid carcinoma is relative common, originating from the salivary glands of the oral cavity, pharynx and lacrimal glands. But mucoepidermoid carcinoma of nasal cavity, paranasal sinuses and respiratory tract is very rare. In particular, 38 cases of mucoepidermoid carcinoma occurring in the primary sinonasal tract were reported in the English literature, but only one case of mucoepidermoid carcinoma arising from the nasal cavity has been previous reported to date in the Korean literature. Recently, we experienced a 51-year-old man presenting with progressive nasal obstruction and recurrent epistaxis. He was diagnosed as mucoepidermoid carcinoma extending into the inferior turbinate in the nasal cavity and it was excised with nasal endoscope. We present the clinical characteristics and therapeutic methods of this case with a review of the literature.
