A 54-year old man was hospitalized with such acute complaints, as vomiting, fatigue, severe gastric pain, progressive weight loss. Gastric cancer was suspected, but the severity of the patient's state excluded X-ray examination of the stomach. The death occurred on day 9 of the hospital stay. It was only the microscopic pathoanatomic examination of the stomach and small intestine, that revealed trichinosis. Absence of Trichinella larvae in the gastric mucosa was suggestive of a massive alimentary infection in the patient.
