Neuroendocrine tumours

Neuroendocrine tumours (NET's) represent a large spectrum of disease. They consist of a large heterogeneous group of malignancies that are derived from embryonic neural crest tissue found in various organ such as the hypothalamus, pituitary gland, thyroid gland, adrenal medulla, and gastrointestinal tract. 

The spectrum of neuroendocrine turmours range from:

Pathology

They can also be divided by their biochemical behaviour as functioning or non-functioning, by their aggressiveness as slow-growing and more aggressive lesions and so on.

Because of secretory products by amine precursor uptake and decarboxylation (APUD) they are also known as APUDomas, which is more historical and no longer used.

Genetics

Mostly occur sporadically, some are linked to multiple endocrine neoplasia syndromes.
