Pheochromocytoma

Pheochromocytoma is a type of neuroendocrine tumor that grows from cells called chromaffin cells. These cells produce hormones needed for the body and are found in the adrenal glands. The adrenal glands are small organs located in the upper region of the abdomen on top of the kidneys. Pheochromocytomas/paragangliomas may be caused by mutations of one of at least ten different genes: the RET gene, which is also associated with multiple endocrine neoplasia type 2; the VHL gene, which is also associated with von Hippel-Lindau syndrome; the neurofibromatosis (NF1) gene, associated with neurofibromatosis
