The incidence of cancer in the paranasal sinuses is about 25% of the malignant tumors of the head and neck region.
Most of them are squamous cell carcinomas, but adenocarcinoma is also recognized.
—We have treated three patients with adenocarcinoma in the nasal cavity and paranasal sinuses.
1) Case 1: A 70-year-old man treated by total maxillectomy and radiation has been alive for six years.
2) Case 2: A 49-year-old man treated by only partial maxillectomy has been alive for four years and one month.
3) Case 3: A 25-year-old man treated by chemo-radio-surgical therapy, died of recurrence and general metastasis.
Surgical therapy should be tried, because radiation is not completely effective, except in cases of adenoacanthoma.
