Exfoliative dermatitishttps://en.wikipedia.org/wiki/Erythroderma
Exfoliative dermatitis is an inflammatory skin disease with redness and scaling that affects nearly the whole body surface. This term applies when 90% or more of the skin is affected.

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, such as the use of topical steroids. Primary manefestation is less frequent and is usually seen in cases of cutaneous T-cell lymphoma. Because it is important to differentiate it from cutaneous T cell lymphoma, a biopsy is performed.

Erythroderma is a rare but serious skin condition. While the exact cause is often unknown, it can be triggered by a drug reaction or an underlying cancer. One common cancer linked to exfoliative dermatitis is cutaneous T-cell lymphoma, which might not show symptoms for months or even years after the skin condition starts. Usually, hospitalization is needed for initial assessment and treatment. Patients with drug-induced disease generally have a good long-term outlook, though cases without a clear cause tend to have a recurring and remitting course. The prognosis for cases linked to cancer typically depends on how the cancer progresses.
