En grupp karcinom med typisk morfologi, ofta bestående av aggregat eller trabekulära skikt av runda, blåaktiga celler, granulärt kromatin och uttunnat ytterskikt av svagt avgränsad cytoplasm. Neuroend okrina tumörer omfattar karcinoid cancer, småcelliga karcinom, medullära sköldkörtelkarcinom, Merkelcellstumörer, neuroendokrina hudkarcinom, öcellstumörer och feokromocytom. Tumörcellerna innehåller neurosekretoriska granuler.
A group of carcinomas which share a characteristic morphology, often being composed of clusters and trabecular sheets of round "blue cells", granular chromatin, and an attenuated rim of poorly demarcated cytoplasm. Neuroendocrine tumors include carcinoids, small ("oat") cell carcinomas, medullary carcinoma of the thyroid, Merkel cell tumor, cutaneous neuroendocrine carcinoma, pancreatic islet cell tumors, and pheochromocytoma. Neurosecretory granules are found within the tumor cells. (Segen, Dictionary of Modern Medicine, 1992)
