Benign Melanoma of the Choroid in a Beagle: Ophthalmological, Light and Electron Microscopical Investigations

Abstract

A pigmented choroidal tumor was diagnosed in a 13-month-old male beagle. The tumor was observed ophthalmoscopically over a period of seven years. Light and electron microscopical features are those of a benign melanocytic tumor with marked histological similarities to uveal nevus in man.
