title: [A case of three malignant tumors of the duodenal bulb and large intestine].
abstract: A 75-year-old woman with anemia admitted to our hospital and was found to have a polyp in the duodenal bulb. The biopsy specimen was histologically diagnosed as an adenoma. A barium enema examination showed an obstruction in the ascending colon and a biopsy done on a specimen of the ascending colon revealed colonic cancer. A histology of the resected specimen of the duodenal bulb revealed a tubular adenocarcinoma in an adenoma, and a similar examination of a colonic resected specimen revealed a mucinous, papillary carcinoma. A primary malignant tumor in the duodenum is an uncommon tumor and our case is first in Japan showing three malignant tumors with an early duodenal cancer.
