Malignant epithelioma of the ciliary body.

A rare case of malignant epithelioma of the ciliary body (verified histologically) is described. Some difficulties of clinical diagnosis are mentioned as well as the general properties of this kind of tumor, which mostly requires an anatomical investigation for recognition. As a special feature of this kind of tumor the precocious consecutive cataract is mentioned; this arises in cases of melanomas of the ciliary body considerably later in the course of malignant growth.
