Pediatric choroidal melanoma in a 13-year-old girl--a clinical masquerade.

Ocular melanoma is the most common primary ocular malignancy, of which uveal melanomas comprise up to 60%; however, uveal melanoma is rare in children. We present the case of a 13-year-old girl with unilateral choroidal mass initially thought to be a traumatic choroidal hematoma, later clinically suspicious for medulloepithelioma, but histologically proven to be melanoma.
