Ipsilateral ethmoid sinuses metastasis and proptosis: Rare presentation of metastatic prostate cancer

Metastatic paranasal sinuses and orbital cancer is very rare. The patient with sinusitis and orbital symptoms warrants a detailed history, complete physical examination and serial radiological tests (sinus radiographs and CT scan) to rule out any metastatic disease and prompt treatment. We present a case of 65 years old patient with metastatic prostate cancer who presented to us with left ethmoid sinuses and orbital metastasis causing ipsilateral proptosis.
