[Non-specific cecal ulcer in a patient with chronic renal failure in hemodialysis treatment. Case report].

We report a 65 years old female undergoing hemodialysis, presenting with intense pain in the lower right quadrant and moderate hematochezia. Since symptoms did not abate after an appendectomy, a colonoscopy and barium enema were performed, whose results suggested an advanced cecal carcinoma. Biopsies were negative for cancer. A new surgical abdominal exploration disclosed a cecal inflammatory and transmural lesion. A right colectomy was performed and the patient had a satisfactory postoperative evolution. Pathological study of the surgical piece showed a six cm perforated profound ulceration and a two cm ulcer. Both had precise limits. Unspecific cecal ulcers are rare entities that must be born in mind in the differential diagnosis of abdominal pain or hematochezia, specially in patients undergoing chronic hemodialysis.
