| Abstract: | A 12-year-old boy presented with an incidental finding of an iris lesion after blunt injury. Ocular examination revealed a large atypical brown vascular nodule in the nasal iris, extending to the pupillary margin. There were smaller scattered nodules scattered within the iris and anterior chamber. Ultrasound biomicroscopy examination revealed no tumour behind the iris. Fundal examination findings were normal. Sector iridectomy revealed mixed spindle and epitheliod melanoma. The eye was enucleated. Histopathologic examination confirmed malignant melanoma confined to the iridocorneal angle, iris, ciliary body and inner layer of the anterior sclera. Iris melanomas are very rare in the prepubertal age group. |
