A Case of Biphenotypic Sinonasal Sarcoma Found in a Young Woman’s Nasal Cavity / 대한이비인후과학회지

ABSTRACT

Biphenotypic sinonasal sarcoma (BSNS) is a newly recognized, very rare malignant tumor of nose and paranasal sinuses, which usually occurs in women. This tumor contains both neural and muscle tissue in the tumor tissue. It is an invasive disease occuring locally in the nasal cavity. However, if not found early, it can spread along the facial structure, for instance, the orbit, skull base, intracranium, and the oropharynx. This tumor is an uncommon disease that has not been reported in Korea to date. We report a case of a 35-year-old female recently diagnosed with BSNS with a review of the literature.
