Background
An extended distribution of neuroendocrine cells explains an extremely diverse tumoral localization of this tumoral lineage. There are neuroendocrines cells in adrenal medulla, anterior pituitary, gastroenteric tube, pancreas, aortic and carotid bodies, parathyroid and neural tissue, thyroid, torax and some tumors with variable differentiation like prostate and breast. Some of these tumors are associated with syndromes such as von-Hippel-Lindau, Neurofibromatosis or MEN syndromes.
Some of them are hormonally active, classified as either syndromic (functioning) or nonsyndromic (nonfunctioning), on the basis of clinical and laboratory findings.
