Abstract
We report a case of pleomorphic adenoma on the nasal septum that recurred after 17 years. 25-years-old female complained of left epistaxis. A tumor had arisen from the nasal septum. The CT scan showed a 21× 12mm soft tissue mass in the anterior left nasal cavity. The pathological diagnosis was a pleomorphic adenoma. We remove the tumor with endoscopic surgery. The tumor recurred 17years after the initial operation. The tumor was multilocular with a maximum size of 35× 27mm and was accompanied by bone destruction of the nasal septum. Therefore, due to the possibility of malignancy, the tumor was removed by lateral rhinotomy. Pathological findings showed a tumor with abundant stromal components, which is considered to be prone to recurrence.
