"Watermelon stomach" in patients on chronic hemodialysis.

"Watermelon stomach" is a common name for gastric antral vascular ectasia (GAVE syndrome). This endoscopic finding is characterized by the appearance of parallel longitudinal red columns along mucosal folds, along with capillars dilatation and hemorrhagy. Finding reliable method for its recognition is of paramount importance. Patient B.D., a 54-year-old woman, developed renal failure, which led to hemodialysis treatment, on the basis of pyelonephritis chronica. As a consequence of the gastrointestinal bleeding, the patient had black stools and developed severe anemia. The endoscopic finding showed the existence of visible columns of vessels transversing the antrum in longitudinal folds and converging in the pylorus, with clear red spots and surrounding hyperemy covered by drops of fresh blood. The diagnosis of "watermelon stomach" was confirmed after the pathohistological examination of the tissue taken at the biopsy, followed by total gastrectomy. Postoperative status was normal, without gastrointestinal hemorrhagia, and she went on with hemodialysis. Before the surgery she received 105 blood transfusions, and after surgical treatment she has received only 18 so far. At the moment she is in good health condition, and on hemodialysis. The reason we have reported this case of "watermelon stomach" syndrome in patient with chronic renal failure is to indicate that this rare anomaly of gastric blood vessels can lead to gastrointestinal blood loss in these patients. Since it is often the reason for many wrong diagnoses, it should be also taken into consideration in cases like these.
