title: Enlargement of a histologically documented choroidal nevus.
abstract: An elevated pigmented mass of the choroid remained stable for 6 1/2 years and then was documented photographically to have increased in size. The tumor stained on fluorescein angiography, produced a visual field defect, and differentially took up radioactive phosphorus. The eye was enucleated and on histologic examination contained a nevus of the choroid. This case shows that enlargement of a choroidal nevus may occur during adulthood, and suggests that despite newer and more sophisticated diagnostic techniques, large nevi and small melanomas of the choroid may be clinically indistinguishable.
