Sweet syndrome as a cutaneous manifestation in a patient with Erysipelothrix rhusiopathiae bacteremia: A case report.

ABSTRACT

Erysipelothrix rhusiopathiae is a gram-positive bacillus causing three clinical syndromes in humans, including localized cutaneous infection, diffuse cutaneous form, and systemic infection. Various skin lesions in systemic form have been reported; however, no comprehensive study has been conducted. Here we report a case of a 60-year-old woman who suffered from E. rhusiopathiae bacteremia with distinct generalized annular purplish plaques. Negative microbiological studies of the lesional skin sample combined with the histopathological study showing diffuse neutrophilic infiltration confirm the diagnosis of Sweet syndrome. This study documents Sweet syndrome as one of the cutaneous manifestations in systemic E. rhusiopathiae infection.
