Austrian dermatologists from the 19th century. They described a pustulous disease, to which they gave their name. It was a severe form of herpes, which arose as a complication of atopic dermatitis. The term "Kaposi-Juliusberg variform pustulosis" is often used by French dermatologists. English-speakers prefer to use "eczema herpeticum" (see this term).
KeratinocyteA type of epithelial cell; the major cells of the epidermis. Others are melanocytes, which are responsible for the skin's color, and Langerhans cells which are part of the immune system. The fundamental function of the epidermis is keratinization. This is the gradual transformation of keratinocytes into flat, dehydrated, anucleated cells. These make up the stratum corneum, which fulfills the role of barrier function. These 'dead' keratinocytes (or more precisely speaking, mature), are shed off outside the body. This 'desquamation' is normally invisible. In certain circumstances, it can cause squamae, scales or flakes.
Keratosis pilarisA common skin complaint, which is seen as small raised bumps around each hair follicle, giving the skin a rough, 'grated' appearance. Keratosis pilaris is most commonly seen on the thighs and the outside of the arms. Keratosis pilaris is common in atopic dermatitis; it is one of the minor criteria for diagnosis (and thus has little importance).
