In 1966 Williams et al. described the combination of mucosal neuromas, pheochromocytoma and medullary thyroid carcinoma. [ citation needed ] In 1968 Steiner et al. introduced the term "multiple endocrine neoplasias" (MEN) to describe disorders featuring combinations of endocrine tumors and proposed the terms 'Wermer syndrome' for MEN 1 and ...
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 .
Pheochromocytoma is a neoplasm composed of cells similar to the chromaffin cells of the mature adrenal medulla. Pheochromocytomas occur in patients of all ages, and may be sporadic, or associated with a hereditary cancer syndrome , such as multiple endocrine neoplasia (MEN) types IIA and IIB, neurofibromatosis type I, or von Hippel–Lindau ...
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.
Von Hippel-Lindau (VHL) disease is classified into two main types based on the presence or absence of pheochromocytoma (pheo). VHL type 1 is characterized by the absence of pheo, while VHL type 2 encompasses individuals with pheo and is further divided into three subcategories: type 2A, type 2B, and type 2C. [19]
When the same type of tumor is found in the adrenal gland, they are referred to as a pheochromocytoma. They are rare tumors, with an overall estimated incidence of 1 in 300,000. [1] There is no test that determines benign from malignant tumors; long-term follow-up is therefore recommended for all individuals with paraganglioma. [2]
Pheochromocytoma originates from chromaffin cells and is a kind of neuroendocrine tumor. [11] Pheochromocytomas are generally benign. 10% to 15% of pheochromocytomas have the potential to be cancerous. [12]
