Acute generalized exanthematous pustulosis induced by iodinated contrast media: a case report.

Acute generalized exanthematous pustulosis (AGEP) is a rare pustular eruption commonly triggered by drugs. It is characterized by acute onset of pustules on erythematous-edematous skin and often presents with fever. This report describes AGEP following exposure to iodinated contrast media (ICM), specifically iobitridol, in a 68-year-old male with multiple comorbidities. The patient developed characteristic erythematous patches with pustules on the body after initial CT imaging with ICM for a prostate abscess. Histological findings and recurrence following re-exposure confirmed AGEP, which was attributed to ICM. This case emphasizes the need for awareness of ICM as a potential trigger for AGEP. Management included topical steroids and antihistamines, resulting in a rapid recovery.
