Pheochromocytoma is a rare tumor of the adrenal medulla composed of chromaffin cells and is part of the paraganglioma (PGL) family of tumors, being defined as an intra-adrenal PGL . [2][4][5] These neuroendocrine tumors can be sympathetic, where they release catecholamines into the bloodstream which cause the most common symptoms, including ...
Specialty. Oncology. Multiple endocrine neoplasia type 2 (also known as "Pheochromocytoma (codons 630 and 634) and amyloid producing medullary thyroid carcinoma", [1] "PTC syndrome," [1] and "Sipple syndrome" [1]) is a group of medical disorders associated with tumors of the endocrine system. The tumors may be benign or malignant (cancer).
Medullary thyroid cancer is a form of thyroid carcinoma which originates from the parafollicular cells (C cells), which produce the hormone calcitonin. [1] Medullary tumors are the third most common of all thyroid cancers and together make up about 3% of all thyroid cancer cases. [2] MTC was first characterized in 1959.
H&E stain. Specialty. Endocrinology. Multiple endocrine neoplasia type 2B (MEN 2B) is a genetic disease that causes multiple tumors on the mouth, eyes, and endocrine glands. It is the most severe type of multiple endocrine neoplasia, [2] differentiated by the presence of benign oral and submucosal tumors in addition to endocrine malignancies.
Multiple Endocrine Neoplasia type 1 (MEN1) is a rare hereditary endocrine cancer syndrome characterized primarily by tumors of the parathyroid glands (95% of cases), endocrine gastroenteropancreatic (GEP) tract (30–80% of cases), and anterior pituitary (15–90% of cases). [19] Other endocrine and non-endocrine neoplasms including ...
Neuroendocrine tumors (NETs) are neoplasms that arise from cells of the endocrine (hormonal) and nervous systems. They most commonly occur in the intestine, where they are often called carcinoid tumors, but they are also found in the pancreas, lung, and the rest of the body. Although there are many kinds of NETs, they are treated as a group of ...
Those who started hormone therapy later in life were already at risk of heart problems and cancer, says Dr. Pinkerton, which skewed the results and made hormone therapy seem more dangerous than it ...
Von Hippel–Lindau disease (VHL), also known as Von Hippel–Lindau syndrome, is a rare genetic disorder with multisystem involvement. [3] It is characterized by visceral cysts and benign tumors with potential for subsequent malignant transformation. It is a type of phakomatosis that results from a mutation in the Von Hippel–Lindau tumor ...
