Iris Melanoma in a 6-Year-Old Girl

Arch Ophthalmol. 2001;119(5):780-781. doi:10.1001/archopht.119.5.780

A GIRL AGED 5 years 10 months was incidentally seen in the clinic while accompanying her mother to a routine eye examination. An elevated brown mass was seen in the lower temporal quadrant of the iris of her right eye, which was suspicious for iris melanoma. Replying to a question, the mother reported a wedge-shaped pigmented area in the child's blue iris since birth. No other ocular melanosis was noted. There was no family history of malignancy.

At her first visit in the ocular oncology clinic, the girl's visual acuity was 20/25 OU, using picture cube. The left eye was normal. The pigmented lesion in the inferotemporal part of the iris of the right eye (Figure 1) was 2.5 × 3.5 mm in diameter. The rest of the right eye examination showed no abnormal findings. Ultrasound biomicroscopy examination revealed an elevated (2.3-mm thickness) solid mass in the iris periphery, occupying the anterior chamber angle without involvement of the ciliary body (Figure 2). Because of the young age of the patient and the history of early pigmented iris lesion, follow-up was recommended.
