The microscopic evaluation revealed gastritis in 50 specimens (43.48%), 61 (53.04%) had normal mucosa, and 4 cases presented pathologies: 3 cases of hyperplastic polyps (2.61%) and 1 neuroendocrine microtumor (0.09%) with two G1 neuroendocrine tumor (NET) foci, with proliferation index lower than 1%, mitotic index lower than 1 and high chromogranine and synaptophysin reaction, and diffused neuroendocrine hyperplasia with dysplasia in the rest of the mucosa. Here, SYP is linked to gastritis.
