RESUMEN
A 66-year-old woman who had been suffering from chronic anorexia for two years was transported to the hospital after being unable to consume food for three days. She had no hematemesis or abdominal pain and had no history of taking nonsteroidal anti-inflammatory drugs. Blood tests showed marked anemia with hemoglobin of 3.3 g/dL, and esophagogastroduodenoscopy revealed a large ulcer lesion in the lesser curvature of the gastric body and a liver-like mass protruding from the ulcer base. Biopsy of the mass showed proliferation of cells showing irregular cord-like structures, suggestive of normal liver tissue or hepatocellular carcinoma. Computed tomography scan showed no obvious free air in the abdomen. Despite conservative treatment, the patient developed hematemesis and progressive anemia, and surgery was performed (total gastrectomy with partial hepatectomy). Surgical specimen showed an ulcer lesion with fibrosis and loss of wall structure in all layers of the stomach, and liver adhesion with fibrosis deep in the ulcer, but no malignant findings. With the advent of powerful gastric acid secretion inhibitors, gastric ulcer invasion into the liver is now very rare, and this case is thus a valuable example showing very clear images.
