[Choroidal metastasis revealing pulmonary adenocarcinoma].

Lung cancer is the first cause of choroidal metastasis in man. Generally, its discovery is made at end-stage of the disease. It can be uncommonly the presenting sign as in our case. We report a case of a 28-year-old patient with no prior medical history. He presented with visual decrease and metamorphopsia that lead to the diagnosis of a metastatic adenocarcinoma of the lung (bone, liver, choroid, nodles). Chemotherapy permitted to improve visual acuity, in parallel with disappearance of choroidal metatasis. Discovery of choroidal tumor should evoke in first line metastasis. Chemotherapy can improve visual acuity and the quality of life.
