A case of primary septal adenoid cystic carcinoma was reported. A 55-year-old man, farmer, complained of a severe nasal bleeding. The posterior half of nasal cavities were full of tumor, but the site of origin was not confirmed because of much bleeding. The CT scan suggested that it was arose and localized in the posterior septum. Histopathological examination showed adenoid cystic carcinoma of cribriform pattern. He received 60Co irradiation (6200 rads) combined with 5-fluorouracil, but the tumor was radioresistant relatively. Then it was completely removed with a sufficient amount of normal septal tissue by Denker's method. No recurrence and distant metastasis were noted for 7 months after the surgery. As the course of adenoid cystic carcinoma is very prolonged, it is necessary to follow up for more than 5 years.
The primary septal adenoid cystic carcinoma is extremely rare, only 5 cases have been reported in the world on our search of literatures.
The CT scan is very useful to determine a tumor invading region in the nose and paranasal sinuses.
