Pancreatic neuroendocrine tumors
Indian Journal of Gastroenterology, 2012Pancreatic neuroendocrine tumors (pancreatic NETs) are rare, low- to intermediate-grade neoplasms thought to arise from the pancreatic islets. Recent advances in pathology and our understanding of the biological behavior of this group of tumors has resulted in changes in their nomenclature and how we treat them.

Pulmonary Neuroendocrine Tumors
Surgical Pathology Clinics, 2020Pulmonary neuroendocrine tumors represent a morphologic spectrum of tumors from the well-differentiated typical carcinoid tumor, to the intermediate-grade atypical carcinoid tumor, to the high-grade neuroendocrine carcinomas composed of small-cell carcinoma and large-cell neuroendocrine carcinoma.

Duodenal neuroendocrine tumors
Khirurgiya. Zhurnal im. N.I. Pirogova, 2019Significant augmentation of the incidence of duodenal neuroendocrine tumors duodenum has been observed in recent decades. There are 5 histological types of these tumors: gastrinoma (50-60%), somatostatin-producing tumor (15%), inactive serotonin-containing tumors (20%), poorly differentiated neuroendocrine carcinoma (

Gastric carcinoids are rare neuroendocrine tumors, usually classified as type I, if associated with atrophic body gastritis; type II, if associated with Zollinger-Ellison syndrome and multiple endocrine neoplasia type I, and type III, in the absence of any gastric pathology (sporadic tumors).

Thymic neuroendocrine tumors are rare and account for approximately 2% to 5% of all thymic tumors. Despite the suggestion of benign behavior implied by their name, thymic carcinoids have been noted to present a more aggressive biologic behavior than their counterparts in other sites.

Bronchopulmonary neuroendocrine tumors
Cancer, 2008AbstractBronchopulmonary neuroendocrine tumors (BP‐NETs) comprise ≈20% of all lung cancers and represent a spectrum of tumors arising from neuroendocrine cells of the BP‐epithelium. Although they share structural, morphological, immunohistochemical, and ultrastructural features, they are separated into 4 subgroups: typical carcinoid tumor (TC ...

Pathology Case Reviews, 2006
Abstract: Neuroendocrine (NE) tumors include a morphologically and functionally diverse family of neoplasms that can arise in virtually all tissues and organs. Although early studies suggested a neural crest origin for all NE tumors, the term NE simply describes a shared phenotype notable for the expression of multiple genes encoding a wide spectrum ...

Journal of Computer Assisted Tomography, 2014
Several classification systems for neuroendocrine tumors (NETs) exist, which use variable terminology and criteria for grading and staging. This variability in terminology can cause confusion and difficulty in recognizing which tumors are, in fact, members of this heterogeneous group of malignancies.

Tumor Markers in Neuroendocrine Tumors
Digestion, 2000Most neuroendocrine tumors produce and secrete a multitude of peptide hormones and amines. Some of these substances cause a specific clinical syndrome: carcinoid, Zollinger-Ellison, hyperglycemic, glucagonoma and WDHA syndrome. Specific markers for these syndromes are basal and/or stimulated levels of urinary 5-HIAA, serum or plasma gastrin, insulin ...
