Erythroderma is defined as a generalized skin disorder characterized by reddening and scaling of 100% of the skin. It is also known as erythrodermatitis, generalized exfoliative dermatitis, and red man syndrome. There may also be normal areas of skin present.

[edit] Causes

Erythroderma is produced by several skin diseases, such as psoriasis, contact dermatitis, drug reactions, and mycosis fungoides (a cutaneous lymphoma). A dermatologist must first diagnose the cause, usually with a skin biopsy, a blood smear examined by a pathologist and patch testing (if the eruption can be temporarily cleared).

[edit] Treatment

The treatment is dependent on the cause.
