A Case Report of Adenocarcinoma of Meckel's Diverticulum

A case of adenocarcinoma of Meckel's diverticulum is reported. A 58-year-old male was admitted to our hospital because of abdominal pain and vomiting. A plain X-ray film showed bowel obstruction. Its location, however, was not revealed by contrast X-ray studies of an upper gastrointestinal series and the large bowel. Shortly after a transient remission, his bowel obstruction relapsed and laparotomy was done. A hen-egg sized tumor was found on the anti-mesenteric side of the ileum, 80 cm oral from Bauhin's valve and obstructing the intestinal lumen. Peritoneal dissemination was obserbed. Partial resection of the ileum including the main tumor was performed. Pathological examination of the resected specimen revealed that the tumor, showing poorly differentiated adenocarcinoma, arose from a genuine diverticulum, presumed to be Meckel's and occupied its entire cavity. There was neither ectopic gastric mucosa nor pancreatic tissue.
