[Epithelial-cystic nevus of the conjunctiva (Parinaud's dermo-epithelioma)].
The epithelio-cystic nevus of the conjunctiva, initially improperly denominated by Parinaud dermo-epithelioma, is a dysplasia circumscribed at the level of bulbar conjunctiva, characterized by its forming of epithelial cysts which develop in a base layer made of nevoid cells. This affection evolves by forming epithelial cysts mostly muciparus ones, when the tumor is sited rather far from the limbus, where multiple chaliced cells are to be found in the epithelium, and as simple epithelial cysts, mostly in the epidermis, when it is sited near the limbus where chaliced cells are scarcer. In this condition the setting of the epithelial compound takes the form of full lobules. The nevoid compound represents the capital element which establishes the diagnosis. The epitheliocystic nevus of conjunctiva is a benign dysembryo with excessive development of epithelial cells in a basic layer of nevoid cells. This affection is benign, but its morphologic diversity and its many denominations give rise to periodical debates.
