Erythroderma refers to the inflammation of the skin involving more than 90% of the body surface area. The most common cause of erythroderma is underlying inflammatory skin conditions such as psoriasis, atopic dermatitis and photodermatitis. Other common aetiologies include infections, cutaneous adverse drug reactions, autoimmune disorders and cutaneous T-cell lymphomas. Diagnostic approach should include a thorough history and clinical examination. Skin biopsies are often needed in the diagnostic workup. Management of erythroderma among others include removal of the offending cause, assessment of fluid balance, maintenance of skin barrier function, nutritional evaluation and exclusion of secondary infection.
This presentation covers a practical review of the aetiology, diagnosis, and treatment of erythroderma.
