하비갑개에서 기원한 비부비동 미분화암종의 내시경적 절제술 1예

Sinonasal undifferentiated carcinoma (SNUC) is an extremely rare, highly aggressive malignancy of the nasal cavity and paranasal sinuses. Although early symptoms of SNUC mimic benign nasal or sinus disease, but SNUC is a rapidly expanding tumor. Patients often present with advanced state. Historically, a cure rate of less than 20% is reported, with most patients dying within 1.5 years despite aggressive multimodality treatment. We recently experienced a 29-year-old male patient diagnosed as SNUC that has originated from the inferior turbinate of right nasal cavity, which was resected using nasal endoscope successfully, and report this case with a review of the literature.
