Acute febrile neutrophilic dermatosis (Sweet's syndrome) caused by minocycline.

Sweet's syndrome (acute febrile neutrophilic dermatosis) occurred in a 29-year-old woman with acne. Although Sweet's syndrome initially seemed to be triggered by an acute acne flare, minocycline could later be identified as the causal agent. Because this could be confirmed in an oral provocation test, this seems to be the first case of a true connection between Sweet's syndrome and its induction by a drug, namely minocycline.
