Introduction:
Human Salmonella infections have been classically distinguised into diseases caused by typhoidal
and non-typhoidal salmonella (NTS). Typhiodal salmonella includes S. enterica serovars Typhi and Paratyphi that cause the
systemic disease but are restricted to human infections, while NTS consists mainly of other serovars that predominantly
cause self-limiting gastroenteritis in humans. Localisation of foci with persisting infection occurs due to dissemination of the
bacteria throughout the body and can cause a variety of rare clinical syndromes at aberrant sites. Fournier’s gangrene, a rapidly progressive, often fatal, necrotizing fasciitis of the external genitalia and perineum due to Salmonella Typhimurium, is a
rare manifestation and has never been reported.
Case:
A 22-year-old male, apparently healthy patient with no relevant past medical history presented to surgical emergency
with chief complaints of swelling of bilateral scrotal area. Infective etiology was considered and a diagnosis of fournier’s
gangrene was made. Pure growth of Salmonella Typhimurium was obtained after repeated subculture and was identified biochemically and on serotyping, as Salmonella enterica serotype Typhimurium using specific antisera.
Conclusion:
In our case report, we describe a case of fournier’s gangrene due to Salmonella Typhimurium in an otherwise
healthy male to highlight the unusual presentation of Non typhoidal salmonellae at an aberrant site. We also emphasize the
importance of using selective media like Selenite F broth for isolation of Salmonella Typhimurium from a pus sample.
