Definition

A well differentiated, low grade neuroendocrine tumor (carcinoid tumor) that arises from the stomach. The vast majority of cases arise from the corpus-fundus region. The mitotic count is less than 2 per 10 HPF and/or the Ki67 index is equal to or less than 2 percent. It may be associated with autoimmune chronic atrophic gastritis, multiple endocrine neoplasia type 1, or it may be sporadic.
