SYNCHRONOUS COLON CANCER PRESENTED AS ADULT ILEO-CAECAL INTUSSUSCEPTION, A RARE CASE REPORT

Abstract

Colorectal cancer (CRC) is the third most common tumor 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 tumors are respectable. These tumors can present as an incidental ndings on screening colonoscopy, with anemia symptoms such as general weakness and fatigue ( for right sided- tumors) or changes in bowel habits ( for left sided tumors). In advanced cases, loss of weight and loss of appetite are also common presenting symptoms. Less common, yet emergent presentations include large bowel obstruction, severe gastrointestinal hemorrhage and free intra-abdominal perforation. Synchronous CRC (SCRC) tumors, dened as two or more primary tumors existing independently of one another, have an incidence rate of 2.3% - 12.4% of overall CRC with male predominance. Presentation of these tumors 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 SCRC tumor in a 32-year-old man, with indication for emergent surgery being ileo-caecal intussusceptions but incidentally was diagnosed to have sigmoid colon growth .
