MEDULLO-EPITHELIOMA

Medullo-epithelioma (diktyoma) of the eye.

Adult type of medullo-epithelioma of the ciliary body.

Three different types of tumors are known to develop from the pars ciliaris reti­ nae: the benign Fuchs epithelioma, the ma­ lignant medullo-epithelioma of the embry­ onic type, and the malignant medullo-epi­ thelioma of the adult type. Chart 1 indicates the relationship of these tumors to the prim­ itive retinal elements and to the tumors of other parts of the retina. The Fuchs epithelioma sim...

Benign calcifying epithelioma.

A BENIGN calcifying epithelioma is a subcutaneous tumour, first described by Malherbe and Chenantais (1880), who called it l'epitheliome calcifie des glandes sebacees. Malherbe (1881, 1905) added more details, but only four examples of such tumours have been reported in the ophthalmic literature (Ashton, 1951; Kornblueth and Liban, 1955). Histological examination of material from the Radcliffe ...

But Krompecher's choice of term may be justified on the ground that basal-cell epithelioma is composed of basal cells which retain their morphological characters throughout their existence, in contrast to the squamous-cell carcinoma in which the basal ce...
