Gastric cancer: problems in histogenesis.
Intestinal metaplasia in the mucosa adjacent to a gastric carcinoma suggests that some carcinomas of the stomach might arise from metaplastic mucosa, as well as the existence of a gastric cancer with morphological features resembling intestinal mucosa. In this study, the extent of intestinal metaplasia of adjacent mucosa, the type of intestinal metaplasia (complete or incomplete), the degree of tumour differentiation, the type and quantity of mucins secreted by neoplastic cells and morphological features of the tumours were evaluated in 59 cases of gastric carcinoma. An analysis of the findings suggests that a carcinoma may arise in the stomach with features of association with incomplete metaplasia and histochemical and histological patterns which mimic carcinomas of the large intestine.
