Sweet's syndrome associated with Yersinia enterocolitica infection

Acute febrile neutrophilic dermatosis (Sweet's syndrome) was diagnosed on the basis of typical clinical and histological features in a 45-year-old woman. Gastrointestinal symptoms had preceded the dermatosis, and an intestinal infection with Yersinia enterocolitica could be proven by culture and serology. This first report on an association between Yersinia infection and Sweet's syndrome widens the spectrum of both infectious diseases possibly inducing acute febrile neutrophilic dermatosis and dermatological manifestations of yersiniosis.
