비외접근법으로 제거한 비중격에서 발생한 편평상피암 1예

초록

Primary tumors arising solely from the nasal septum are quite unusual. Moreover, malignanttumors arising from the nasal septum are rare and represent less than 9% of sinonasal malig-nancies. Of all reported cases of nasal septum carcinoma, squamous cell carcinoma is the mostcommon type. Due to the rare prevalence, its clinical course and prognosis are not well estab-lished. In this article, we report a case of a 79-year-old male with nasal obstruction. Endoscopicexamination showed an exophytic mass obstructing the right nasal cavity accompanied bypolypoid mass in the left nasal cavity. Punch biopsy confirmed the diagnosis of squamous cellcarcinoma by histopathology. Radiologic evaluation showed a large nasal cavity mass involv-ing the nasal septum. The tumor was removed using the external rhinoplasty approach with alarge septal resection, saving the nasal keystone area and the columella to prevent the external nose deformity.
