Isolated ulcerative skin lesion caused by Salmonella Weltevreden.

Salmonella enterica serovar Weltevreden is not a commonly isolated serotype in India. We report isolation of Salmonella Weltevreden, from an unusual site--an ulcer on the gluteal region of a patient who had undergone coronary artery bypass surgery. To our knowledge, Salmonellae have never been reported to cause isolated ulcerative lesions on the skin. This is the first report of an isolated ulcerative lesion on the skin caused by Salmonella Weltevreden. Our findings indicate that there may be modes of pathogenesis of Salmonella infections that we are yet unaware of. Further work and extensive reporting of all Salmonella infections are necessary to elucidate these mechanisms.
