A report is presented on a metastatic adeno-carcinoma of the iris. The patient, a 62-year-old healthy male, noted slight visual disturbance in the right eye for the past 2 weeks. Ophthalmo-logical examinations revealed the presence of a small-grayish-white mass with a number of ves-sels on the iris surface at the 4 o'clock position near the periphery. The corrected visual acuity and the intraocular pressure were normal. The left eye was also free of pathological findings.

X-ray studies of the chest showed signs of lung carcinoma in spite of absence of general symptoms.
