[Endocrine cells in gastric carcinoma].
A few endocrine cells were observed in 7 of 16 specimens of gastric carcinoma studied by electronmicroscopy. They were closely mixed with other types of tumor cells infiltrating into the stroma. Some endocrine cells contained both neuroendocrine and mucous granules. This conforms well to the hypothesis that the endocrine cells as well as other types of tumor cells in gastric carcinoma, originate from the endoderm. The endocrine cells and other varieties of tumor cells were found in both intestinal and diffuse types of gastric carcinoma. The heterogeneity and histogenesis of gastric carcinoma are discussed.
