Adenocarcinoma of the ileocecal valve: report of a case.

Tumors of the ileocecal valve are rarely mentioned, and are mostly defined radiologically. In this manuscript, we report a case of ileocecal valve adenocarcinoma diagnosed endoscopically. The case is a male patient, 78-years-old, with abdominal pain and weight loss in whom a mass was palpated in the lower right quadrant. Abdominal ultrasound examination followed by colonoscopy and pathological diagnosis revealed adenocarcinoma of the ileocecal valve confirmed by surgical diagnosis. We report this case because of its rarity and because there is no endoscopic image in the medical literature.
