Men Syndromes
Multiple Endocrine Neoplasia (MEN) syndromes are inherited disorders characterized by tumors in multiple endocrine glands, with MEN1, MEN2A, and MEN2B being key examples.
MEN SYNDROMES (Multiple Endocrine Neoplasia)
- The MEN syndromes can be remembered by their characteristic tumor patterns. MEN1 is associated with the 3 Ps : Parathyroid hyperplasia/adenoma, Pancreas islet cell tumors (such as gastrinoma or insulinoma), and Pituitary adenomas (most comm
- A MEN1 mutation is found in 30–35% of sporadic parathyroid adenomas, highlighting its broader clinical relevance beyond the full syndrome.
- Given the high risk of medullary thyroid carcinoma, a RET mutation in MEN2 syndromes necessitates screening of family members, often leading to prophylactic thyroidectomy in carriers to prevent disease progression.
- It is crucial to always screen patients diagnosed with phaeochromocytoma for MEN2 syndromes, as it is a common component of these genetic conditions.

MEN SYNDROMES (Multiple Endocrine Neoplasia)
- MEN1 = 3 Ps — Parathyroid + Pancreas + Pituitary
- MEN2A = 2 Ps — Parathyroid + Phaeochromocytoma + medullary thyroid
- MEN2B = Phaeochromocytoma + medullary thyroid + marfanoid/neuromas (no parathyroid)
