Abstract
In the paranasal sinuses, metastatic carcinoma is far less common than primary carcinoma. Metastasis of prostate cancer to the paranasal sinuses is very rare. The author describes a case of prostatic adenocarcinoma that metastasized to the frontal and ethmoid sinuses in a 68-year-old man. The patient was treated with radiotherapy but was lost to follow-up after 3 months.
