title: Descending colo-colonic intussusception secondary to signet ring cell carcinoma: A case report.
abstract: The incidence of intussusception is low in adults, particularly in the descending colon, due to the anatomical attachment of the descending colon to the retroperitoneum. Signet ring cell histology represents ~1% of colon adenocarcinomas and is associated with young patients and a poor clinical outcome. The present study describes a case of descending colo-colonic intussusception caused by signet ring cell carcinoma in a 27-year-old male. The patient presented with a history of intermittent left upper-quadrant abdominal pain for more than six months without any evident etiology. A computed tomography scan of the abdomen revealed left-sided colo-colonic intussusception. Upon laparotomy, a left hemicolectomy was performed according to intraoperative frozen-section pathology. Post-operative pathological evaluation revealed signet ring cell carcinoma invasion of the serosa, and 31.8% (7/22) of the regional lymph nodes were positive for cancerous cells. The post-operative course was uneventful and the patient was discharged on the tenth post-operative day.
