Case Discussion
Neuroendocrine tumors (NETs) represent a wide spectrum of diseases. They consist of a large heterogeneous group of malignancies that are derived from embryonic neural crest tissue found in various organs such as the hypothalamus, pituitary gland, thyroid gland, adrenal medulla, and gastrointestinal tract.
Metastatic neuroendocrine tumors of the liver are far more common than primary hepatic neuroendocrine tumors.
