Corneal epithelial dysplasia and carcinoma in situ. 1981

A F Cruess, and S M Wasan, and W E Willis

Corneal epithelial dysplasia and carcinoma in situ have not been emphasized as distinct clinical conditions in the literature. Seven cases are presented with their clinicopathological correlation. Six of the patients presented primarily with corneal signs and symptoms consisting of notable visual blurring or foreign body sensations, or both. Biomicroscopic examination revealed a geographic, diffuse, greyish-white haze involving the corneal epithelium, often with; subtle thickening and irregularity of the involved areas and overlying superficial punctate keratitis. Histologic examination showed all degree of corneal epithelial dysplasia up to carcinoma in situ. The diagnosis, course and management of these conditions is discussed.

D001913	Bowen's Disease	A persistent progressive non-elevated red scaly or crusted plaque which is due to an intradermal carcinoma and is potentially malignant. Atypical squamous cells proliferate through the whole thickness of the epidermis. The lesions may occur anywhere on the skin surface or on mucosal surfaces. The cause most frequently found is trivalent arsenic compounds. Freezing, cauterization or diathermy coagulation is often effective.

D002278	Carcinoma in Situ	A lesion with cytological characteristics associated with invasive carcinoma but the tumor cells are confined to the epithelium of origin, without invasion of the basement membrane.

D003315	Cornea	The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.
