title: Menetrier's disease presenting with iron deficiency anemia.
abstract: Menetrier's disease (MD) or polyadenomes en nappe is a form of hypertrophic gastropathy occurring primarily in middle-aged males. Patients generally present clinically with dyspepsia and, on occasion, with hypoproteinemic edema and anemia. The latter feature, when combined with the radiographic appearance of the stomach in MD, can lend to confusion with carcinoma and malignant lymphoma. To illustrate this diagnostic problem, a case is reported of a 41-year-old female who initially presented to her family physician with symptoms of easy fatigue and dyspnea on exertion and signs of pallor and ankle edema. Pertinent laboratory findings included a hemoglobin of 2.8 g/dL, hematocrit of 10.3 percent, mean corpuscular volume of 63.4 mu 3, a serum albumin of 2.7 g/dL, and heme positive stools. Endoscopic examination revealed a circumferential polypoid mass involving the cardia and fundus of the stomach with relative sparing of the antrum. A CT scan of the abdomen and pelvis showed a large mass in the stomach which the radiologists and gastroenterologists believed probably represented a lymphoma or gastric carcinoma. A total gastrectomy specimen exhibited features of MD. Routine bright-field microscopy and immunohistochemical reactivity for transforming growth factor-alpha confirmed the diagnosis of MD. Moreover, ulceration of the tips of some of the hypertrophied gastric folds provided an explantation for the iron deficiency anemia. Awareness that MD may present with anemia will help in the differential diagnosis with lymphoma and carcinoma.
