why carcinoid tumours occurs in atrophic gastritis??

  #2

The precurser lesion to such "early carcinoids", as well as to infiltrating carcinoids, is probably hyperplasia of endocrine cells in the atrophic fundic mucosa. Such hyperplasias, whether nodular or diffuse, are quantitatively related to hypergastrinaemia, which is a typical feature of antrum sparing (type A) atrophic gastritis.
