He was referred with the presumptive diagnosis of abdominal sarcoma for surgical evaluation and treatment. He underwent a Hartmann\u2019s procedure with resection of the sigmoid colon and formation of an end colostomy. Multiple tissue samples were taken from the mass for histopathological examination. The correct diagnosis was made after pathological examination by detection of actinomycetes colonies. Penicillin-based therapy was commenced and continued for six months, when a CT revealed complete resolution of the pre-operative findings without any evidence of a mass.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Although rare, actinomycosis should be considered in the differential diagnosis of colonic neoplastic lesions.
