[A case of adenocarcinoma of the lung presenting symptoms of choroidal metastasis as the initial clinical manifestation].

A 51-year-old woman was referred to our hospital with a complaint of disturbance in vision. Ophthalmologic examination revealed multiple choroidal tumors. High-resolution CT showed a nodular shadow in the left lower lobe. Transbronchial biopsy and right supraclavicular lymph node biopsy specimens showed a poorly-differentiated adenocarcinoma. We concluded that the choroidal tumors had metastasized from the lung. Combined chemotherapy (CDDP + CPT-11) followed by irradiation of both eyes and brain were performed. Nevertheless, she died 6 months after the initial presentation. It is important to notice ophthalmologic symptoms because lung cancer may metastasize to the choroids.
