Salmonella gastroenteritis associated with erythema nodosum

Abstract

There are several well established causes of erythema nodosum, and two case reports of erythema nodosum occurring after salmonella gastroenteritis have suggested that this infection may be an additional cause. Both cases seem to have been isolated ones; admission to hospital was necessary in both. In October 1981 an outbreak of Salmonella typhimurium gastroenteritis occurred in our practice, which affected over 700 patients and was bacteriologically proved in 440. During this outbreak three cases of erythema nodosum were seen.
