Acute generalized exanthematous pustulosis/exfoliative dermatitis eruption

Abstract

Severe drug eruption is the most common skin drug adverse reaction in clinic.Immune-mediated adverse drug reactions occur commonly in clinical practice and include mild, self-limited cutaneous eruptions, IgE-mediated hypersensitivity, and severe cutaneous adverse drug reactions.Severe cutaneous adverse drug reactions represent an uncommon but potentially life-threatening form of delayed T cell-mediated reaction.The spectrum of illness ranges from acute generalized exanthematous pustulosis to drug reaction with eosinophilia with systemic symptoms, to the most severe form of illness, Stevens-Johnson syndrome and toxic epidermal necrolysis.Drug-induced exfoliative dermatitis may be one of the manifestations of eosinophilia with systemic symptoms.Typical clinical manifestations, medication history, relevant physical examinations and related auxiliary examinations of patients are helpful to the early diagnosis of the disease.This article introduced in detail the research progress of acute generalized eruptive pustulosis and exfoliative dermatitis eruption.
