Nuclei of neuroendocrine tumors often show granular "salt-and-pepper" chromatin, as seen here on H&E stain and Pap stain. [69] Small intestinal neuroendocrine tumor at bottom third of image, showing the typical intramural (within the wall) location, and overlying intact epithelium. H&E stain.
A paraganglioma is a rare neuroendocrine neoplasm that may develop at various body sites (including the head, neck, thorax and abdomen). When the same type of tumor is found in the adrenal gland, they are referred to as a pheochromocytoma. They are rare tumors, with an overall estimated incidence of 1 in 300,000. [1]
Due to presence of these tumors, DIPNECH is classified as a pre-malignant condition. [1] Although there have been reports of atypical carcinoids with local lymph node involvement, there are no reports of more aggressive neuroendocrine tumors, such as large cell neuroendocrine or small cell lung cancer, associated with DIPNECH.

Neuroendocrine carcinoma of the cervix is best defined separately:Neuroendocrine: Of, relating to, or involving the interaction between the nervous system and the hormones of the endocrine glands. Carcinoma: An invasive malignant tumor derived from epithelial tissue that tends to metastasize to other areas of the body.
Large-cell neuroendocrine carcinoma of the lung (LCNEC of the lung), or pulmonary large-cell neuroendocrine carcinoma (PLCNC), is a highly malignant neoplasm arising from transformed epithelial cells originating in tissues within the pulmonary tree. It is currently considered to be a subtype of large-cell lung carcinoma.
Endocrine-Related Cancer was founded as Reviews on Endocrine-Related Cancer, the in-house journal of Zeneca (now AstraZeneca) published by its parent company ICI Pharmaceuticals. It was taken over by the Society for Endocrinology in 1994 when it was renamed, and the remit was extended to include a limited number of original research articles to ...
Pulmonary neuroendocrine tumors are neuroendocrine tumors localized to the lung: bronchus or pulmonary parenchyma.. Pulmonary neuroendocrine tumors include a spectrum of tumors from the low-grade typical pulmonary carcinoid tumor and intermediate-grade atypical pulmonary carcinoid tumor to the high-grade pulmonary large cell neuroendocrine carcinoma (LCNEC) and pulmonary small cell carcinoma ...
Insulinomas are rare neuroendocrine tumours with an incidence estimated at one to four new cases per million persons per year. Insulinoma is one of the most common types of tumours arising from the islets of Langerhans cells (pancreatic endocrine tumours). Estimates of malignancy (metastases) range from 5 to 30%.
