Minute carcinoid arising in gastric tubular adenoma.
We report a minute carcinoid tumour forming multiple, endocrine nodules or glandular structures and located within a gastric tubular adenoma. The tumour cells were positive for the argyrophilic reaction and a few revealed serotonin immunoreactivity. This case may represent the third histogenetic type of gastric carcinoid tumour.
