After a literature search, we found that liver metastases secondary to prostatic adenocarcinoma are very uncommon, and usually occur in patients presenting a systemic aggressive disease with bone and/or lymph node metastases. After a succinct outline of the types and distribution of the neuroendocrine cells in the normal gastric mucosa we discuss the most common situations in which the pathologist needs to think about gastric neuroendocrine cells.

Meet the TRISH Team. 2019;18(3):21522. Well differentiated neuroendocrine pattern: Monotonous regular cells with round or oval nuclei with salt and pepper chromatin and moderate eosinophilic granular cytoplasm, Organoid architecture: tumor cells arranged in nests, trabecular or insular pattern (, In some cases, nuclear pleomorphism may be encountered (endocrine atypia) but is not associated with tumor aggressiveness (. The cells were uniform, with abundant, focally eosinophilic cytoplasm, regular round nuclei, small nucleoli, with 11 mitoses/10 HPF, and Ki-67 index of 3%. Thus, 3 types of tumors are recognized: type 1 associated with autoimmune chronic atrophic gastritis (A-CAG), type 2 associated with multiple endocrine neoplasia type 1 (MEN-1) and Zollinger Ellison syndrome (ZES), and type 3 sporadic.[12]. 2015 Nov 14;21(42):12179-89. doi: 10.3748/wjg.v21.i42.12179.
