Eczematous Disorders

John R. Ingram


Eczema, also known as dermatitis, is a clinical and histopathological pattern of skin inflammation, which presents as pruritus, skin dryness and erythema. This chapter covers the non‐atopic eczema subtypes, which can be classified based on aetiology and skin site. The main subtypes are: nummular dermatitis, asteatotic eczema, hand eczema, venous eczema of the lower legs, eyelid eczema, juvenile plantar dermatosis and miscellaneous eczematous dermatoses. Eczema may result in skin lichenification and severe eczema is the commonest cause of erythroderma. Quality of life for patients and their families may be considerably reduced and occupational issues may add to the financial consequences. Management of non‐atopic eczema involves the avoidance of any external causes, where relevant, and treatment modalities that are similar to those for atopic eczema, in the context that relatively few clinical trials have been performed for non‐atopic eczema.
