Campylobacter gastroenteritis associated with Sweet's syndrome.

Sweet's syndrome or acute febrile neutrophilic dermatosis has been associated with underlying infection, malignancy, inflammatory disease and certain medications. The infection agents associated with this include Streptococcus species, Yersinia species, Chlamydia species, Salmonella species and Helicobacter pylori. We report a case of Sweet's syndrome in a 73-year-old woman following a 2 week course of severe gastroenteritis caused by Campylobacter species. Histological examination of skin lesions showed marked inflammatory infiltrate throughout the dermis, composed of neutrophils and histiocytes. The patient was successfully treated with topical and systemic steroids. To date, this is the first case of Sweet's syndrome to be reported linked to Campylobacter species to our knowledge.
