title: [A case of metastatic iris tumor from lung cancer presenting as decreased vision].
abstract: We presented a case of metastatic iris tumor from lung cancer first presenting as decreased vision. A 47-year-old male was referred to our hospital, complaining of decreased vision. At his first visit, a yellowish mass was found on the right iris, and chest X-ray revealed paratracheal, subcarina, and right hilar lymphadenopathy. Bronchoscopy was performed, and small cell carcinoma was detected in a transbronchial biopsy specimen. Sixteen cases of metastatic iris tumor from lung cancer have been reported of such rare occurrences in Japan. The clinical features are briefly reviewed.
