Acute generalized exanthematous pustulosis (AGEP) is now a well known
clinical entity, characterized by acute onset with associated fever, a
nd numerous non-follicular pin-head sterile pustules on erythematous b
ackground. The biopsy evidences subcorneal pustules resembling those o
f pustular psoriasis. However, polymorphic aspects such as pseudo eryt
hema multiforme purpuric lesions, and edema are often associated, and
with the rapid self-healing course of this impressive pustulosis, allo
w the differential diagnosis with pustular psoriasis. Most cases of AG
EP are drug induced, particularly by antibiotics and mainly beta-lacta
ms. However, a number of other drugs, of which the list is increasing,
may be responsible. Few cases are related to other causative factors
such as viral infections or ultraviolet radiation. Copyright (C) 1996
