Neuroendocrine neoplasms, also neuroendocrine tumours, are a group of tumours whose behaviour varies from benign to malignant and are found in may different sites.

Use of the term carcinoid

Use of the term carcinoid is discouraged.[1][2][3]

Microscopic - generic

Features:

  • Nests of cells.
  • Stippled chromatin AKA salt-and-pepper chromatin, coarse chromatin.
  • Classically subepithelial/mural.
