Descending colo-colonic intussusception secondary to signet ring cell carcinoma: A case report

Adult ileocecal intussusception as an unusual presentation of ascending colon adenocarcinoma: a case report from Sudan

Adult colonic intussusception, is a rare entity that is typically associated with underlying organic pathologies, notably colorectal tumors, unlike pediatric cases, which are mostly idiopathic. We present a unique case of a 42-year-old female with ascending colon adenocarcinoma, where ileocecal intussusception served as the initial clinical manifestation. The patient's non-specific symptoms, familial history of colon cancer and subsequent diagnostic evaluations underscore the importance of considering malignancy in such presentations. Successful laparoscopic right hemicolectomy resolved the intussusception. This case, which is the first case to be reported in Sudan, highlights the clinical complexities of adult colonic intussusception, emphasizing the need for a heightened index of suspicion for underlying malignancy and the significance of timely surgical intervention. Furthermore, the challenges encountered in resource-limited settings underscore the necessity for genetic testing to guide familial screenings and identify hereditary factors contributing to colon cancer, providing valuable insights for clinicians managing similar cases.

A Rare Case of Signet Ring Cell Colon Cancer Presenting as Adult Colorectal Intussusception

Signet ring cell carcinoma of the rectum is rare and typically presents with advanced disease. We report a case of a 68-year-old man who presented with left lower quadrant pain and was found to have signet ring cell carcinoma with intussusception. This case is unusual because of its polypoid growth pattern and apparent early pathological stage. We discuss the differential diagnoses and prognosis.
