Menetrier's disease (protein-losing gastropathy) in a child with acute lymphoblastic leukemia

Abstract A 3-year-old boy with high-risk precursor-B ALL presented with abdominal pain, vomiting, and hypoalbuminemia just before his second scheduled course of high-dose methotrexate in interim maintenance. Examination was significant for epigastric tenderness and periorbital edema. Abdominal imaging revealed a circumferential thickening of the stomach with an increased mucosal enhancement and a mild circumferential thickening of segments of small bowel loops. Cytomegalovirus (CMV) of the patient, determined by PCR, in blood was positive with a low titer and was subsequently negative. Upper endoscopy revealed hypertrophic rugae and folds in the stomach and duodenum, and biopsy showed giant gastric folds and foveolar hyperplasia but was negative for CMV. He received supportive care and a 2-week course of ganciclovir and Cytogam with clinical improvement. We report a case of Menetrier's disease (Protein-losing gastropathy), which was diagnosed in a child with acute leukemia. Menetrier's disease should be considered in any patient with symptoms referable to the gastrointestinal tract and thickened stomach and bowel loops detected by radiologic imaging.
