Close communication between the histopathologist and clinician is required, with an analysis of the relevant clinical data, correlated with histologic analysis of tumor and nontumor tissue. Histological assessment of gastric tumor and liver metastasis: (A) large nodules of uniform cells with neuroendocrine features in the antral mucosa (HE, 4); (B) positive cells for chromogranin; (C) liver biopsy with large nodules of neuroendocrine cells, with pseudoglandular architecture (HE, 4); (D) liver biopsy with positive cells for chromogranin (2). However, our patient had AMAG with G-cell hyperplasia that had progressed to type 1 GNET, thereby increasing the risk of developing metastatic disease. The prognosis was good in case 1, whilst poorer outcomes were associated with more aggressive tumors in case 2 and case 3. g-NENs are rare tumors with distinct clinical and histological features.

Surgical treatment is recommended for patients with type 2 g-NETs, primarily directed to underlying disease (removal of gastrinomas, in order to reduce the ECL cells stimulation). Rectal neuroendocrine tumors are increasingly being diagnosed since the implementation of screening colonoscopy in 2000. [11,12], In contrast with most of the digestive NENs, gastric tumors may have a specific clinical context, with distinct prognosis and therapeutic management. 2014 Jan;43(1):34-5.

[2830] The possibility of vascular invasion and metastases endorses the role of endoscopic ultrasonography in the assessment of the depth of tumoral invasion and lymph nodes involvement, especially in tumors greater than 10 to 20 mm in size. This leads to the absence of gastric acid production, which causes compensatory hyperplasia of gastric antral G-cells leading to hypergastrinemia. Marques B, Raquel G, Martins RG, et al. Ann Surg. This leads to the absence of gastric acid production causing compensatory hyperplasia of gastric antral G-cells with hypergastrinemia.10 Furthermore, there is potentially decreased inhibition from gastric D-cells, contributing to increased gastrin production. La Rosa S, Rindi G, Solcia E, Tang LH. [17] In our patient with CAG and type 1 g-NET, endoscopic resection of the largest tumor and endoscopic surveillance were recommended (case 1).
