Poorly differentiated features, tumoral necrosis, Tumors with neuroendocrine (tumor or carcinoma) and adenocarcinoma components of 30% each, Some use size criteria < 5 mm as a definition for hyperplasia and > 5 mm is the minimum size necessary to diagnose a NET, Some may diagnose NET when grossly there is a polyp / nodule regardless of size in the absence of other explanatory findings, Other criteria have been proposed for microscopic proliferations: if there is nodular growth of ECL cells > 150 microns or if there is a conglomeration of nodules, signs of microinfiltration or new stroma, then the lesion has been proposed to be classified as dysplasia or Tis, Ki67 and mitotic figure count, whichever is higher, Ki67 and mitotic figure count, whichever is lower. [20,21] Each marker has a different specificity and sensitivity.

In this case, our patient with diabetes, autoimmune thyroiditis, and pernicious anemia was found to have positive antigastric parietal cell and anti-intrinsic factor antibodies with gastric biopsy findings consistent with AMAG. [9], Gastric NENs were classified using the 2010 WHO classification of digestive NENs, which consists of a grading system, independently of the immunoprofile of the proliferating cells: grade 1 neuroendocrine tumors (G1 NETs), grade 2 neuroendocrine tumors (G2 NETs), G3 neuroendocrine carcinomas (NECs), and mixed adenoneuroendocrine carcinomas.
