title: [A case of metastatic carcinoma to the retina].
abstract: The authors report a case of metastatic carcinoma to the retina. The patient was a 61-year-old man who had an operation for a well-differentiated adenocarcinoma of the rectum. Ophthalmoscopic examination disclosed a single, white, elevated mass lesion surrounded by serous retinal detachment located in the upper part of the macula of the right eye. A few retinal hemorrhages existed around the lesion. Fluorescein angiography revealed partially obscured retinal vessels due to compression by the tumor and arteriovenous anastomosis. Postmortem pathologic examination confirmed metastases to the brain, lung and retina. Microscopic examination showed a retinal lesion and tumor cells in the right eye. Tumor cells, similar to the carcinoma of the rectum, were present only in the neurosensory retina and did not invade the pigmented epithelium or choroid.
