A 63-year-old woman suffered a short period of nausea and vomiting. X-ray examination of the upper gastrointestinal tract was suspicious of scirrhus carcinoma of the stomach. At operation the suspicion was strengthened, and total gastrectomy was performed. Microscopic examination showed chronic, granulomatous gastritis compatible with Crohn's disease. The patient died on the 8th day postoperatively with caval thrombosis obliterating the inlet to the right auricle. No other localization of the disease could be demonstrated on thorough microscopic and macroscopic examination of the whole gastrointestinal tract.
