Neuroendocrine neoplasms of the stomach [PDF]
Biomedical Papers, 2014 Gastric neuroendocrine neoplasms of type 1 and type 3 are different entities and as such require different therapeutical strategies. The aim of this study was to define and distinguish these two tumour subtypes with clearly different biological properties and patient survival.

Neuroendocrine neoplasm H&E histology and immunohistochemical staining.
, 2023 H&E stained gallbladder neuroendocrine neoplasm (A). Neoplastic cells exhibited positive immunoreactivity for chromogranin A (B), neuron specific enolase (C), and synaptophysin (D); cytokeratin 7 staining was negative (E) and few neoplastic cells were Ki-

Neuroendocrine neoplasm update: toward universal nomenclature
, 2020 Neuroendocrine neoplasia is described in almost every tissue, either in the pure endocrine organs, the nerve structures or in the so-called diffuse neuroendocrine system. The current nomenclature contains time-honored widely accepted definitions; however,

Transgelin immunofluorescent staining of canine gallbladder neuroendocrine neoplasm.
, 2023 Nuclei are labeled by Hoescht stain (blue, left panel). Gall bladder neuroendocrine neoplasm demonstrates cytoplasmic positive transgelin (green, middle panel and right panel) immunofluorescence compared to negative control (normal canine liver), wherein

A rectal neuroendocrine neoplasm
Revista Española de Enfermedades Digestivas, 2017 The incidence of gastric and rectal carcinoids is increasing. This is probably due to endoscopic screening. The prognosis is primarily dependent upon tumor size, aggressiveness (pathology, Ki-67), metastatic disease and stage. However, neuroendocrine carcinoma usually behaves as an adenocarcinoma.

Neuroendocrine neoplasms of the esophagus and stomach [PDF]
Pathologica, 2021 Esophageal neuroendocrine neoplasms (E-NENs) are much rarer than other gastro-entero-pancreatic neuroendocrine neoplasms, the majority showing aggressive behavior with early dissemination and poor prognosis. Among E-NENs, exceptionally rare well differentiated neuroendocrine tumors (E-NET) and more frequent esophageal poorly differentiated ...
