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.
Images:
- Neuroendocrine tumour - low mag. (WC).
- Neuroendocrine tumour - intermed. mag. (WC).
- Neuroendocrine tumour - high mag. (WC).
