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]
A plasma level of metanephrines should be checked before surgical thyroidectomy takes place to evaluate for the presence of pheochromocytoma since 25% of people found to have medullary thyroid cancer have the inherited form from the MEN2A syndrome. Undiagnosed pheochromocytoma leads to a very high intraoperative risk of hypertensive crisis and ...

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 ...
