title: [Contribution to the epithelial tumors of the ciliary body (clinical, histopathological and electronmicroscopical observation) (author's transl)].
abstract: An adenoma of the non pigmented epithelium of the ciliary body was supposed to be an irisciliary body melanoma (32P-test positive) and was treated by irido-cyclectomy. Vision acuity remained 0,4 one year after operation. The tumor formed adenoid tubes lined with a cubical or cylindrical epithelium. The cytoplasm of all tumorcells was threaded with compactly arranged tonofilaments. The histopathological examination showed unequivocal the benignant character of this tumor. Nevertheless the tumorcells were infiltrating the deep scleral layer in one place. Also the lens was deformed by the tumor and developed a local opacity in the periphery. It is refered to the difficulty of a clear histopathological distinction between adenomas, adenocarcinomas and pseudo-adenomatous hyperplasia of the ciliary body (Fuchs adenoma).
