Nausea and vomiting are symptoms frequently seen in normal pregnancy. We report a patient with gastric carcinoma who presented with severe hyperemesis gravidarum that led to extreme volume depletion, hypertension, proteinuria, and acute renal failure. A 35-year-old woman (para 2-1-0-1) with a prenatal course significant for persistent nausea, vomiting, and poor weight gain presented at 36 weeks' gestation with elevated blood pressure (157/114 mm Hg), proteinuria (4+), hypochloremic metabolic alkalosis, and severe intravascular volume contraction. A presumptive diagnosis of severe preeclampsia was made, the patient was given intravenous MgSO4, and cesarean delivery was accomplished uneventfully. When significant emesis persisted in the postoperative period, esophagogastroduodenoscopy revealed an antral/prepyloric mass with a biopsy-proven poorly differentiated adenocarcinoma. To our knowledge, this is the first report of a case of hyperemesis gravidarum with gastric cancer masquerading as preeclampsia.
