[Acute generalized exanthematous pustulosis with confirmed type IV allergy. Report of 3 cases]. / Akute generalisierte exanthematische Pustulose bei nachgewiesener Typ-IV-Allergie: Bericht über 3 Patienten.

Acute generalized exanthematous pustulosis (AGEP) is characterized by an acute disseminated eruption of multiple, non-follicular pustules. In addition, it can be associated with fever, elevated erythrocyte sedimentation rate, and leukocytosis. The pathogenesis of AGEP is still unknown; however, medications appear a likely cause in most cases. We report on 3 patients with AGEP demonstrating characteristic clinical and histologic features after taking amoxicillin, ampicillin, or diltiazem. All patients had positive patch test reactions to the suspected drugs.
