Two cases of primary carcinoma of the frontal sinus are reported. The first patient, a 77-year-old male was referred with painful swelling in the right frontal region. The histopathological study of the specimen in the nasal cavity revealed undifferentiated carcinoma. Irradiation therapy and removal of the tumor were performed and no recurrence was observed for 5 years after treatment.
The second patient, a 69-year-old male had visited our clinic with a complaint of swelling and pain around the left eye. The histopathological diagnosis was squamous cell carcinoma. Total removal of the tumor with exenteration of the left eye ball was performed, since the mass infiltrated inside of the orbita.
A Kyusor technique was used to remove the tumor that infiltrated in the dura mater during surgery.
