eczema

Definition eczema

eczema: eczema n. a superficial inflammation of the skin, mainly affecting the *epidermis. Eczema causes itching. with a red rash often accompanied by small blisters that weep and become crusted. Subsequent scaling, thickening, or discoloration of the skin may occur. the disorder has several forms, with two major divisions: eczematous dermatitis, which results from external factors (see dermatitis); and endogenous (or constitutional) eczema, occurring without any obvious external cause. Classification of endogenous eczema is based on its appearance and site. the five types are atopic, commonly found in childhood and sometimes associated with a family history of allergy; discoid, characterized by small well-defined areas of eczema; pompholyx, found on the hands and feet; seborrhoeic, in which scaly plaques occur in areas of the greatest sebum production (the scalp, face, etc); and varicose. which develops on the legs in association with poor circulation. Treatment of eczema depends on the cause but usually includes the use of locally applied corticosteroids. -eczematous adj.
