Occlusive stenosis – atypical presentation of right colon cancer

Abstract

Colorectal cancers are one of the most frequent malignancies worldwide. Significant differences are described in relation to the location of tumors within the colon. Thus, between right and left colon cancer there are epidemiological, clinical, genetic, evolutionary and prognostic differences. Considering these premises, right and left colon cancers can be seen as distinct pathological entities. In right colon cancer the initial phases are often asymptomatic and the presence of symptoms is in relation to advanced phases and complications. We report the case of a 64-year-old man with no significant medical history who was admitted and operated as an emergency for stenotic and perforated tumor of the right colon. Operative exploration revealed distended small bowel loops and caecum up to the ascending colon where a stenosing tumor is found. The tumor extends to a small bowel loop and also exhibit a perforation. Right hemicolectomy was performed, with favorable postoperative evolution and discharge on 7th day.
