Abstract:
An extensive range of diseases or reactions can cause pustular eruptions of the skin. Drug-provoked cutaneous eruptions includes acute generalized exanthematous pustulosis (AGEP) and acneiform eruption. We report a 50-year-old man who developed fever and a sudden eruption of widespread pustules 12 days after ingestion of celecoxib prescribed for a prolapsed intervertebral disc. AGEP was diagnosed based on the typical history, characteristic features, and laboratory findings. However, histopathological findings were consistent with folliculitic drug reaction pattern without features of AGEP. We present, the first known reported case of folliculitic drug reaction pattern caused by celecoxib.
