Can erythema nodosum and reactive arthritis be a sequel to Shigella flexneri gastroenteritis?
Erythema nodosum and seronegative arthritis associated with diarrhoea was previously regarded as implying the presence of inflammatory bowel disease. Recently, however, erythema nodosum has been described as a sequel to diarrhoea caused by infection with Salmonella typhimurium, Yersinia enterocolitica and Campylobacter jejuni. We report two patients in whom erythema nodosum and reactive arthritis followed acute Shigella flexneri gastroenteritis, a rare association.
