Abstract

We report a case of ciliary body melanocytoma in a Korean patient, which presented as an intermittently painful pigmented iris mass and was successfully managed by iridocyclectomy. A 52-year-old healthy man presented with an irregularly-shaped and heavily-pigmented mass at the iris root of his right eye. Visual acuity of the right eye was 20/20 with normal intraocular pressure. Ultrasound biomicroscopy showed a 1.5x1.3-mm ciliary-body mass with extension into the iris root. Iridocyclectomy with scleral resection under a lamellar scleral flap was performed, and the histopathologic features of the resected tissue were consistent with melanocytoma of the ciliary body. The patient's visual acuity remained 20/20 with good postoperative cosmesis. During one year of follow-up, no signs of tumor recurrence were seen, and the patient reported resolution of the intermittent ocular pain in the involved eye.

Medium internal reflection of the mass was seen with a basal diameter of 1.5 mm and a height of 1.3 mm. (B) Microscopic appearance of the specimen showing polyhedral cells filled with dark melanin granules, typical features of a melanocytoma.
