Abstract
Acute generalized exanthematous pustulosis (AGEP) is manifested by rapid development of many sterile, nonfollicular pustules on a background of edematous erythema. More than 90 percent of AGEP are induced by medication, mostly antibiotics. Drug patch test can be helpful in the diagnosis of AGEP. This paper reports the first case of celecoxib-induced AGEP confirmed by patch test in Korean literature.
