title: Clinicopathologic manifestations of 36 korean patients with acute generalized exanthematous pustulosis: a case series and review of the literature.
abstract: BACKGROUND
  Acute generalized exanthematous pustulosis (AGEP) is a rare and severe subtype of drug eruption, characterized by acute, extensive, non-follicular, sterile pustules on an erythematous background, accompanied by fever and leukocytosis.
  
  
  OBJECTIVE
  The purpose of this study was to characterize AGEP in Korean patients in terms of clinical, laboratory, and pathologic findings.
  
  
  METHODS
  Thirty-six patients (M:F=17:19) with AGEP were identified from an extensive review of medical records over a 15 year period. All patient cases were confirmed by biopsy and fulfilled the diagnostic criteria.
  
  
  RESULTS
  The patient ages ranged from 4~80 years (37.6+/-19.4). The incubation period was 1~23 days. The duration of disease was 5~14 days. Neutrophilia (36/36), high CRP (14/36), and eosinophilia (30/36) were common laboratory findings. A history of drug administration existed in 23 of 36 patients; herbal medications, lacquers and radiocontrast media were the unique causative drugs. Spongioform subcorneal or intraepidermal pustules in the epidermis was observed in all patients. Thirty-six patients were subdivided into 2 groups: group A (n=23) was strongly associated with known agents; and group B (n=13) had no identified causative agents. There was no significant difference between the 2 groups.
  
  
  CONCLUSIONS
  OUR RESULTS DEMONSTRATE THE CHARACTERISTIC FEATURES OF AGEP IN KOREAN PATIENTS AS FOLLOWS: lower identification of causative agents; herbal medications, lacquers, and radiocontrast media were the main causative agents; and no significant differences existed between the 2 groups.
