Abstract:
Intestinal duplications are rare developmental abnormalities that may occur anywhere in the gastrointestinal tract. The possibility of a malignant change occurring in these duplications is very low. We present a case of adenocarcinoma arising in a duplication of the cecum. A 41-year-old male patient was admitted because of a palpable abdominal mass. Abdominal computed tomography revealed a 6-cm, peripheral wall-enhanced, round, cystic mass in the cecal area. Excision of the mesenteric mass and a right hemicolectomy was performed. Upon histologic examination, the patient was diagnosed with adenocarcinoma arising in a duplication of the cecum.

Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...
