Thoracic Surgery Clinics, 2014
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 ...

Pulmonary Neuroendocrine Tumors
Surgical Pathology Clinics, 2010Pulmonary neuroendocrine tumors are frequently encountered as small biopsy and resection specimens. Although the World Health Organization (WHO) classification is used as a diagnostic framework globally and in daily practice, it is not without controversy and practical difficulties. The WHO criteria for pulmonary neuroendocrine tumors are reviewed with

Neuroendocrine tumors (NETs) are a diverse group of neoplasms that originate from neuroendocrine cells throughout the body. Diagnosing NETs presents unique challenges due to their varied presentation, morphology, and biological behavior. This article provides an overview of the key diagnostic principles relevant to general pathologists, emphasizing the

Neuroendocrine tumors arise from organs known to secrete neuroendocrine messengers, e.g. hormones or substances with paracrine activity, and/or to contain cells displaying neuroendocrine characteristics or activity. The term “neuro-endocrine” is used here to define the secretory products of the cells and tumors rather than their nature and ...
