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 ...
Oncology, endocrine surgery. Multiple endocrine neoplasia type 1 (MEN-1) is one of a group of disorders, the multiple endocrine neoplasias, that affect the endocrine system through development of neoplastic lesions in pituitary, parathyroid gland and pancreas. [1] Individuals suffering from this disorder are prone to developing multiple ...
MEN1. Menin is a protein that in humans is encoded by the MEN1 gene. [5] Menin is a putative tumor suppressor associated with multiple endocrine neoplasia type 1 (MEN-1 syndrome) and has autosomal dominant inheritance. [6] Variations in the MEN1 gene can cause pituitary adenomas, hyperparathyroidism, pancreatic neuroendocrine tumors, gastrinoma ...

Nearly 25 percent of patients with gastrinomas have multiple tumors as part of a condition called multiple endocrine neoplasia type 1 (MEN 1). MEN I patients have tumors in their pituitary gland and parathyroid glands, in addition to tumors of the pancreas. [6] [citation needed]
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 ).
Adenomas of the anterior pituitary gland are a major clinical feature of multiple endocrine neoplasia type 1 (MEN1), a rare inherited endocrine syndrome that affects 1 person in every 30,000. MEN causes various combinations of benign or malignant tumors in various glands in the endocrine system or may cause the glands to become enlarged without ...
Prolactinoma. A prolactinoma is a tumor ( adenoma) of the pituitary gland that produces the hormone prolactin. It is the most common type of functioning pituitary tumor. [ 1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood ( hyperprolactinemia ), or due to pressure of the tumor on surrounding brain tissue ...
