Erythroderma (also known as "Exfoliative dermatitis," "Dermatitis exfoliativa," and "Red man syndrome") is an inflammatory skin disease with erythema and scaling that affects nearly the entire cutaneous surface.[1]:436[2]:215
In ICD-10, a distinction is made between "exfoliative dermatitis" at L26, and "erythroderma" at L53.9.

The classification of exfoliative dermatitis into Wilson-Brocq (chronic relapsing), Hebra or pityriasis rubra (progressive), and Savill (self-limited) types may have had historical value, but it currently lacks pathophysiologic or clinical utility.[1]:436
Erythroderma is generalized exfoliative dermatitis, which involves 90% or more of the patient's skin.[3] The most common cause of erythroderma is exacerbation of an underlying skin disease, such as psoriasis, contact dermatitis, seborrheic dermatitis, lichen planus, pityriasis rubra pilaris or a drug reaction. Primary erythroderma is less frequent and is usually seen in cases of cutaneous T-cell lymphoma, in particular in Sézary's disease.[4]
The most common causes of exfoliative dermatitis are best remembered by the mnemonic device ID-SCALP. [5] . The causes and their frequencies are as follows:
Differential diagnosis in patients with erythroderma may be difficult.
The treatment is dependent on the cause.
