Sweet's syndrome in association with Crohn's disease: report of a case and review of the literature.

Abstract

A 41-year-old woman developed a skin rash as part of Sweet's syndrome concurrent with the first episode of Crohn's disease of the colon. Sweet's syndrome, acute febrile neutrophilic dermatosis, may be associated with inflammatory, infectious, or neoplastic diseases. Its association with Crohn's disease is very rare, and when reported it has been mainly associated with Crohn's colitis. This association has been described in various stages of the disease. Sweet's syndrome may be considered one of the extraintestinal manifestations of Crohn's disease. Early diagnosis of this dermatosis may be important because of the prompt response to treatment with corticosteroids. The value of metronidazole should be considered because this medication may enhance response to treatment.
