Cancer of the frontal sinus has been known for its rare occurrence and poor prognosis.
The authors report a case of primary cancer of the frontal sinus in a 60-year-old male, that initially appeared to be a frontal sinus cyst which had probably been induced by a previous trauma to the frontal region.
Exposure of the frontal sinus revealed a primary cancer of the sinus, histologically a squamous cell carcinoma.
Postoperative irradiation is underway on this patient.
