The patient was treated with irradiation because of her age. The patient has been alive 4 months after the initial treatment. A 48-year-old male with ethmoidal sinus carcinoma had the complaint of repeated nasal bleeding and swelling in the right margo supraorbitalis. The patient was treated with surgical operation, followed by irradi ation, and chemotherapy.<BR>This surgical operation was performed by an approach from the nasal side and the scalp side because of infiltration into the bone of the skull base. The postoperative histopathology revealed adenocarci n oma.<BR>The patient has been alive 3 months after the initial treatment without any evidence of recurrence of the tumor. Eighty five patients with carcinoma of the paranasal sinuses have been treated in our university. Primary carcinoma of frontal sinus was found in only 1 case (1.2%) and that in ethmoidal sinus was found in 17 cases (20%).
