Uncommon presentation of actinomycosis mimicking colonic cancer: Colon actinomycosis with invasion of the abdominal wall

Actinomycosis is an uncommon chronic suppurative infectious disease that is caused by Actinomycetes organisms, which are gram-positive, microaerophilic, anaerobic bacteria. Herein, we present the case of a 42-year-old female patient who underwent surgical exploration following presentation with abdominal pain and an abdominal mass, initially thought to be a malignancy. Histological examination of the specimen revealed colon actinomycosis. [Arch Clin Exp Surg 2015; 4(2.000): 107-110]
