title: Solitary polypoid hamartoma of the oxyntic mucosa of the stomach.
abstract: A solitary pedunculated polyp of the oxyntic mucosa removed from a 66-year-old patient with atrophic gastritis and achlorhydria exhibited distinctive histological features consisting of submucosal, mostly oxyntic-type glands with a smooth muscular framework. Histochemical and immunohistochemical studies demonstrated that the glands were composed of well differentiated chief, parietal, and endocrine cells. Moreover, less frequent glands of the antro-pyloric type were also seen. The lesion was regarded as a previously unrecognized variety of gastric hamartoma.
