An abdominal actinomycosis was concurred with small intestine perforation by a suspected fishbone

Abstract

A case of an abdominal actinomycosis, seen in a 41-year-old woman, which concurred small intestine perforation suspected to be the result of a fishbone. The patient complained of able tender mass in the right lower quadrant. Explorative laparotomy was performed under a diagnosis of localized abscess. An inflammatory tumor of small intestine mesentery involving the distal ileum and cecum was treated by ileocecectomy. The resected specimen showed small intestine perforation with abscess, which was histologically diagnosed as actinomycosis but we were not able to find any fishbones. We will discuss possible pathogenesis and the therapeutic modalities.
