AMAG is associated with other autoimmune diseases and is a risk factor for the development of type 1 gastric neuroendocrine tumor (GNET).2 Previous studies have reported an annual incidence of type 1 GNET ranging from 0.4% to 0.68% in patients with AMAG.3,4 Lately, the incidence of AMAG and type 1 GNET has increased globally, partly owing to improved awareness of these diseases.5 Type 1 GNET comprises 70%80% of all GNETs and generally has an excellent prognosis after resection, with a metastatic potential between 2% and 5%.6 Despite the relatively benign course of type 1 GNET, careful consideration should be placed on diagnosis and management, given the increasing incidence of these tumors.

Pancreatic Neuroendocrine Neoplasms : General. Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare and poorly understood lung condition that is characterized by the abnormal overgrowth of certain cells in the lung (called pulmonary neuroendocrine cells) that receive signals from nerve cells (neurons) and produce hormones. [14], NETs classification has been a highly debated subject over the years. 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 (.
