A 48-year-old man with Gardner's syndrome, who had abdominoperineal resection for rectal carcinoma in 1962, was found to have an ulcerating growth of the duodenum, and pancreaticoduodenectomy was performed in 1979. Histologic examination by complete step-serial sectioning disclosed a well-differentiated adenocarcinoma with adenomatous remnants, a large adenoma with focal carcinoma, 256 adenomas of the duodenum, and 91 adenomas of the gastric antrum. The world medical literature was reviewed, and 29 cases of periampullary carcinoma and 12 cases of gastric carcinoma complicating familial polyposis coli or Gardner's syndrome were analyzed.

Erythroleukemia and gastric cancer following thorotrast injection.

A 63-year-old male, who had undergone angiography using thorium dioxide (Thorotrast) at the age of 15 for investigation of a giant hemangioma on his left thigh, developed anemia in September 1986 (47 yrs after the angiography). A diagnosis of erythroleukemia was made from a bone marrow study which showed 56.4% megaloblastoid erythroblasts and 12.8% myeloblasts. Autopsy revealed Thorotrast deposition in the liver, spleen, bone marrow, and lymph nodes, and monotonous proliferation of myeloblasts in the bone marrow. He also had differentiated tubular adenocarcinoma of the posterior wall of the stomach.
