[Retrorbital metastasis an initial manifestation of prostatic cancer].

Orbital metastasis is an unusual localization within tumoral dissemination of prostatic cancer. Similarly, it is rare that orbital metastasis might be responsible for the clinic manifestations that determine the initial diagnosis of neoplasia. We illustrate the case of a patient suffering from prostatic adernocarcinoma that displayed alterations of facial sensitivity and right eye exophthalmos. We describe how the final diagnosis was reached and the patient's response to the suppressive hormonal treatment. The patient's rate of survival has proved to be longer than the rest of cases documented, with over 30-month follow-up.
