Six years ago during an endoscopy, the gastroenterologist noted that he had seen a small nodule forming in my stomach.
A recent endoscopy revealed 3 nodules. The biopsies showed that they were benign, but I'm curious as to why I now have 3 of them.
I asked the new gastroenterologist, who spoke very broken English, so it was difficult to understand her. She seemed to be saying that they just "decided" to start aggregating for no known reason.
This is a printout of the biopsy report:
Antral Nodule Biopsy: ===================== Gastric antral mucosa with reactive epithelial changes and few superficial intraepithelial neutrophils, consistent with polypoid foveolar hyperplasia
Searching for "polypoid foveolar hyperplasia" indicates that this could be caused by something called h.pylori infection as well as auto-immune gastritis. However the biopsies came back negative for helicobacter.
So, the question: besides those two, are there any other known causes for this type of hyperplasia?
