Abstract

Acute generalized exanthematous pustulosis (AGEP) is a rare, severe, pustular reaction pattern, attributed mainly to drugs. Other triggers such as infections, spider bite, and contact sensitivity have been implicated. AGEP is characterized by typical morphology, unique histology, and a rapid clinical course. The AGEP validation score (EuroSCAR group criteria) is a useful tool for establishing the diagnosis. The immune pathogenesis involves drug-specific T-cells, neutrophils, and the release of cytokines/chemokines (i.e., IL-8/CXCL8). In view of the remarkable clinical and histological similarity between AGEP and pustular psoriasis, the genetic basis of AGEP should be further evaluated.
