eczema

 [ek´zĕ-mah]
1. any superficial inflammatory process involving primarily the epidermis, marked early by redness, itching, minute papules and vesicles, weeping, oozing, and crusting, and later by scaling, lichenification, and often pigmentation.
2. atopic dermatitis.

Eczema is a common allergic reaction in children but it also occurs in adults, usually in a more severe form. Childhood eczema often begins in infancy, the rash appearing on the face, neck, and folds of elbows and knees. It may disappear by itself when an offending food is removed from the diet, or it may become more extensive and in some instances cover the entire surface of the body. Severe eczema can be complicated by skin infections. Childhood eczema may persist for several years or return after the child is older. Persons suffering from childhood eczema may develop another allergic condition later, most often hay fever or asthma.
Cause and Treatment. Eczema is sometimes caused by an allergic sensitivity to foods such as milk, fish, or eggs. Inhalant allergens such as dust and pollens rarely cause eczema. Treatment involves the use of soothing baths, moisturizing creams, topical steroids, and oral antihistamines to alleviate itching. See also allergy.

ec·ze·ma her·pe·t'i·cum

a febrile condition caused by cutaneous dissemination of herpesvirus type 1, occurring most commonly in children, consisting of a widespread eruption of vesicles that rapidly become umbilicated pustules; clinically indistinguishable from a generalized vaccinia. The two may be distinguished by electron microscopy or demonstration of inclusion bodies in smears, which are intranuclear in eczema herpeticum and intracytoplasmic in eczema vaccinatum.

eczema herpeticum

a generalized vesiculopustular rash caused by herpes simplex virus or vaccinia virus infection of a preexisting rash such as atopic dermatitis. Also called Kaposi's varicelliform eruption.
