Multiple gastric carcinoids and pernicious anemia: report of a case.
A case of pernicious anemia associated with multiple gastric carcinoids is reported. The neoplastic growth was composed of enterochromaffin-like (ECL) cells, and ECL cell hyperplasia was observed also in hyperplastic polyps, inside the fundic glands and in small nests lying in the lamina propria (microcarcinoidosis). The possible relation between pernicious anemia and ECL cell hyperplasia is discussed.
