Pheochromocytoma Synonyms
Pheochromocytoma is a rare tumor that develops in the adrenal glands, which are located on top of the kidneys. This tumor arises from the chromaffin cells, which produce and release hormones like adrenaline and noradrenaline. Pheochromocytoma is also known by several other names, including:
- Adrenaline-producing tumor: This term highlights the tumor's ability to produce excessive amounts of adrenaline, leading to symptoms such as high blood pressure, rapid heartbeat, and sweating.
- Paraganglioma: Pheochromocytoma is sometimes classified as a paraganglioma, which refers to a tumor that arises from the extra-adrenal chromaffin cells. Paragangliomas can occur in various locations outside the adrenal glands, such as the abdomen, chest, or head and neck.
- Adrenal medullary tumor: This name emphasizes the tumor's origin in the adrenal medulla, the inner part of the adrenal gland where chromaffin cells are located.
- Catecholamine-secreting tumor: Pheochromocytomas produce and release catecholamines, including adrenaline and noradrenaline. This term highlights the tumor's ability to secrete these hormones into the bloodstream.
- Neuroendocrine tumor: Pheochromocytoma falls under the category of neuroendocrine tumors, which are tumors that arise from cells of the neuroendocrine system. These tumors can be benign or malignant and can occur in various organs throughout the body.
It is important to note that while these terms are used interchangeably, they all refer to the same condition: a tumor in the adrenal glands that produces excessive amounts of hormones. Pheochromocytoma can cause a range of symptoms, including high blood pressure, palpitations, headaches, sweating, and anxiety. If left untreated, it can lead to serious complications such as heart attack, stroke, or organ damage.
