A 23-year-old white man had a pigmented iris tumor that was not enlarging; it produced satellite iris lesions, diffuse pigmentation of the trabecular meshwork, and secondary glaucoma. Although enucleation was initially recommended, we chose to remove only the primary lesion with a sector iridectomy. Histologically, the lesion proved to be a benign melanocytoma that had undergone extensive necrosis. Postoperatively, the satellite lesions, pigmentation in the angle, and glaucoma all resolved.
