Orbital tumors can present with different symptoms, especially ophthalmic disturbances. We describe 1 patient with an orbital metastasis from prostate carcinoma presenting with proptosis and give details of his presentation, diagnostic tools, and treatment. This is a rare case. Possible ocular spread of prostate adenocarcinoma and the diagnostic techniques used are discussed. It is stressed that immunohistochemical studies and comparison with primary tumor may be essential for a definitive diagnosis. The treatment of prostate orbital metastases is also reviewed.
