title: [Orbital metastasis from mucinous adenocarcinoma of the rectum].
abstract: Orbital metastasis from colorectal cancer are extremely rare. Only six cases are described in the literature. The discrepancy between the frequency of colorectal cancer and the rarity of metastasis to the eye and orbit remains paradoxical and enigmatic. We report the case of an 18-year-old young woman with orbital metastasis as the presenting sign of rectal cancer. Proptosis is the most frequent presenting clinical sign. Once the diagnosis is made, the prognosis is poor and treatment is palliative.
