title: [Mixed carcinoid-carcinoma of the stomach].
abstract: Bioptical observation of a mixed carcinoid-carcinoma in a 75-year-old man's stomach was described. The subcardial tumour was 10-7 cm in diameter with secondaries in perigastric lymph nodes. A well differentiated adenocarcinoma with mucus production formed a minor marginal part of the carcinoid which expressed immunohistochemical markers common in gut cancers: carcinoembryonic antigen, epithelial membrane antigen and some cytokeratins. The well differentiated adenocarcinoma expressed different cytokeratins detected by AE1-AE3 antibody. The carcinoid was positive with Grimelius impregnation and strongly positive with chromogranin A and synaptophysin bound antibodies. Transition of both the tumour types was continuous.
