erythroplasia

erythroplasia

 [ĕ-rith″ro-pla´zhah]
a condition of the mucous membranes characterized by red papular lesions.
erythroplasia of Queyrat a form of epithelial dysplasia, which may range in severity from mild disorientation of epithelial cells with variable cellular pleomorphism to changes of carcinoma in situ and even invasive carcinoma, usually found on the glans penis and prepuce of uncircumcised middle-aged and older men; occasionally it may involve the lips, oral mucosa, tongue, vulva, or glabrous skin. It is typically characterized by the development of a slowly growing, circumscribed, erythematous, usually moist, velvety, and shiny patch.

In 1911, a dermatologist, Louis Queyrat, described lesions of the glans penis that were subsequently named erythroplasia of Queyrat.
Terms that were not recommended "because of the confusion associated with the use" included Bowen disease, erythroplasia of Queyrat, carcinoma simplex, and leukoplakic vulvitis.

Dysplasia, erythroplasia, leukoplasia, lymphomatoid granulomatosis and papulosis, preleukemia and xeroderma pigmetosum are all conditions which, if left untreated, may lead to cancer.
The differential diagnosis of a white plaque on the glans or distal shaft of the penis includes vitiligo, erythroplasia of Queyrat, lichen planus, localized scleroderma, and leukoplakia.
Some conditions, such as cervical dysplasia, erythroplasia or xeroderma pigmentosum are believed to serve as biomarkers for carginogenesis.
This disease must be differentiated by skin biopsy from lichen planus, erythroplasia of Queyrat and leukoplakia, as all are grossly similar.
