MANY nevi of the choroid are difficult to detect clinically and on gross examination of the opened globe in the laboratory. In the series of Naumann et al,1 only 10% of their choroidal nevi were detected clinically. It was also their impression that many amelanotic or lightly pigmented nevi were missed by the pathologist. External examination of the eye in the laboratory normally provides no hint as to the presence of choroidal nevi. Careful transillumination of the globe is the most valuable aid in localizing such pigmented choroidal lesions. This report of a case was prompted by the unusual association of a choroidal nevus with a localized area of proliferation of dendritic melanocytes within the sclera which resulted in a deeply pigmented lesion visible externally.
