title: Choroidal nevus with subretinal pigment epithelial neovascular membrane and a positive P-32 test.
abstract: A 62-year-old white female was found to have a small, flat pigmented choroidal tumor. After fluorescein angiography and a positive P-32 test, the eye was enucleated for presumed malignant melanoma. Histologically, the tumor proved to be a choroidal nevus with a break in Bruch's membrane and a subretinal-pigment-epithelial neovascular membrane.
