BackgroundChoriocarcinoma is an aggressive malignant tumor. It commonly invades the uterus, causing necrosis and hemorrhage through vascular invasion. Metastasis is also common, with the main areas affected being the lung, brain, liver, pelvis, vagina, spleen, intestine, and kidney.ObjectivesTo illustrate the presentation of a rare disease, metastatic choriocarcinoma to the eye, causing a retinal detachment, and to elucidate the characteristics and treatment of that rare disease.Case ReportA 23-year-old woman presented to our Emergency Department with a left painful red eye with decreased visual acuity and was subsequently diagnosed with choriocarcinoma with metastasis to the lungs, brain, and choroid, causing a left exudative retinal detachment.ConclusionGestational choriocarcinoma with metastasis to the eye is a rare disease and a rare cause of exudative retinal detachment. In general, metastatic choriocarcinoma is highly curable with chemotherapy. However, metastasis to the eye, regardless of the type of tumor, portends a poor prognosis.Copyright © 2013 Elsevier Inc.
