title: [Combined malignant carcinoid and adenomas in the operated stomach: the immunohistological study of a case].
abstract: The distribution of carcinoembryonic antigen (CEA), organ specific colonic antigen (C) and two pepsinogens (P) was studied in the peritumorous mucosa and in the tumours (one carcinoid and 3 adenomas) in the stomach of a patient, that had undergone the Bilroth-II resection 10 years before. No antigens were found in the carcinoid. C-antigen was found in the adenomas. The peritumorous gastric mucosa, morphologically not changed contained P, but not C and CEA. Mucosal areas adjacent to the adenomas had dysplastic or metaplastic changes, contained CEA and C, but didn't contain P.
