Synchronous Colon Cancer Presenting as a Different Concomitant Surgical Emergency; Case Report and Literature Review

AbstractColorectal cancer (CRC) is the third most common tumour type worldwide with approximately 1.8 million new cases diagnosed per year. Despite the high incidence of newly diagnosed cases, the majority (70% –80%) of these tumours are resectable. These tumours can present either as an incidental finding during screening colonoscopy or with anaemia symptoms such as general weakness and fatigue (for right sided-tumours) or changes in bowel habits (for left-sided tumours). In advanced cases, loss of weig ht and loss of appetite are also common presenting symptoms. Less common, yet emergent presentations include large bowel obstruction, severe gastrointestinal haemorrhage and free intra-abdominal perforation.Synchronous CRC (SCRC) cancers, defined as two or more primary tumours existing independently of one another, have an incidence rate of 2.3% –12.4% of overall CRC with male predominance. Presentation of these tumours is usually identical to presentation of solitary CRC. Emergency surgical presentation, with two different surgical indications for operation is very rare. Herein, we present a case of a 71-year-old male patient, who presen ted with colonic perforation, as well as colo-colic intussusception due to SCRC tumour. Subtotal colectomy, along with end-ileostomy was done. Histopathological report revealed synchronous colonic mucinous cancer and well differentiated colonic adenocarcinoma.
