[A man with erythema and pustules]. / Een man met erytheem en pustels.

A 47-year-old man presented to the emergency department with a rapidly progressive, generalized rash and pustulosis shortly after he had started amoxicillin/clavulanic acid for the treatment of a pulmonary infection. Based on the patient's history and the clinical symptoms, the diagnosis of 'acute generalized exanthematous pustulosis' (AGEP) was suspected. This was confirmed by histopathological examination. The skin abnormalities slowly disappeared after terminating antibiotic medication.
