Myonecrosis due to gas gangrene without open wounds and severe soft tissue destruction is a rare entity. However, several cases have been reported in literature strongly indicating an association between metabolic disorders or malignancies and gas gangrene [1-24]. In most of these cases Clostridium septicum was identified [2-4,6-12,14,16-20,23], whereas other species are rarely found in spontaneous gas gangrene [1,13,15,21]. The coherence however is only evidence based due to a lack clinical of pathological facts. In cases where a myonecrosis of an extremity occurs together with a localized adenocarcinoma of the colon the possibility of a bacteremia is considered by various authors [2,3,5,7,8,12,14,15,20] but the way of infection remains speculative [2,6,15].
