Grading scheme is based on the proliferative rate (mitoses and Ki67 index) as follows: Low grade or grade 1 (G1): mitoses 2/2 mm, Intermediate grade or grade 2 (G2): mitoses 2 - 20/2 mm, High grade or grade 3 (G3): mitoses > 20/2 mm, Mitotic count should be evaluated in a 2 mm, Ki67 index should be estimated in 500 cells in the hotspot regions (, If there is any discrepancy between mitotic index and Ki67 index, the higher should be considered for the classification (.

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. Tumors develop as multiple polypoid lesions, usually small (<10 mm), in the corpus of the stomach or in the gastric fundus. Macroscopic evaluation of the resected specimen showed multiple nodular lesions in the stomach, protruding from the mucosa, with dimensions between 10 and 60 mm, distributed in the gastric body.
