An unusual presentation of colon cancer in a young individual.

Intussusception occurs rarely in adults. It presents with a variety of acute, intermittent, and chronic symptoms, thus making its preoperative diagnosis difficult. CT scan of the abdomen and pelvis usually reveals the diagnosis of intussusception in adults. Surgical resection of the intussusception without reduction is the preferred treatment in adults, as almost half of both colonic and enteric intussusceptions are associated with malignancy. However, the choice and timing of operation will depend on the clinical condition of the patient and the status of the invaginating tumor. Colon cancer in young individuals is usually aggressive, with a dismal prognosis.
