EA80 — Atopic eczema

ICD-11 EA80 — Atopic eczema

A chronic inflammatory genetically-determined eczematous dermatosis associated with an atopic diathesis (elevated circulating IgE levels, Type I allergy, asthma and allergic rhinitis). Filaggrin mutations resulting in impaired epidermal barrier function are important in its pathogenesis. Atopic eczema is manifested by intense pruritus, exudation, crusting, excoriation and lichenification. The face and non-flexural areas are often involved in infants; involvement of the limb flexures may be seen at any age. Although commonly limited in extent and duration, atopic eczema may be generalised and life-long.

The diagnosis excludes nothing.
