Erythroderma (also known as "Exfoliative dermatitis," "Dermatitis exfoliativa) is an inflammatory skin disease with erythema and scaling that affects nearly the entire cutaneous surface.〔Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). McGraw-Hill. p. 436. ISBN 0-07-138076-0.〕〔James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. p. 125. ISBN 0-7216-2921-0.〕 In ICD-10, a distinction is made between "exfoliative dermatitis" at L26, and "erythroderma" at L53.9. ==Causes== Erythroderma is generalized exfoliative dermatitis, which involves 90% or more of the patient's skin. 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.〔http://books.google.com/books?id=WgkZH4Hse6gC&pg=PA40&dq=erythroderma〕 The most common causes of exfoliative dermatitis are best remembered by the mnemonic device ID-SCALP.〔 The causes and their frequencies are as follows: * Idiopathic - 30% * Drug allergy - 28% * Seborrheic dermatitis - 2% * Contact dermatitis - 3% * Atopic dermatitis - 10% * Lymphoma and leukemia - 14% * Psoriasis - 8% Differential diagnosis in patients with erythroderma may be difficult. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Erythroderma」の詳細全文を読む スポンサード リンク
