This abnormality is a paraneoplastic syndrome (i.e. caused by hyperplasia or tumors). About 35% of the cases are caused by a single aldosterone-secreting adenoma, a condition known as Conn's syndrome. [7] [8] Many patients experience fatigue, potassium deficiency and high blood pressure which may cause poor vision, confusion or headaches.
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 ...
The most recent data indicates that there are 25 pheochromocytoma susceptibility genes; however, just 12 are recognized as part of a well-known syndrome. [9] Determining the genetic status of a pheochromocytoma patient is crucial — each gene is inherited in a different pattern, associated with specific disease characteristics, and may respond ...
An adrenocortical adenoma or adrenal adenoma is commonly described as a benign neoplasm emerging from the cells that comprise the adrenal cortex.Like most adenomas, the adrenocortical adenoma is considered a benign tumor since the majority of them are non-functioning and asymptomatic.
Conductive deafness-ptosis-skeletal anomalies syndrome; Congenital bilateral perisylvian syndrome; Congenital contractural arachnodactyly; Congenital generalized lipodystrophy; Congenital insensitivity to pain; Congenital myasthenic syndrome; Congenital nephrotic syndrome; Congenital rubella syndrome; Conn's syndrome; Conorenal syndrome ...
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]
Gordon et al. reported cases of a difference disease—the "multiple mucosal neuroma syndrome"—having the physical phenotype of MEN2B, but without variations in the RET gene and without malignancy. [15] MEN2B should be entertained as a diagnosis whenever a person is found to have either medullary thyroid carcinoma or pheochromocytoma.
