Multiple endocrine neoplasia (MEN) syndromes
1. Big picture
Multiple endocrine neoplasia (MEN) syndromes are inherited tumor-predisposition syndromes in which a patient develops tumors in several endocrine organs. The exam task is not to memorize every rare tumor, but to recognize the classic combinations:
| Syndrome | Classic exam triad |
|---|---|
| MEN1 | Parathyroid + pancreatic/duodenal neuroendocrine tumors + pituitary adenoma |
| MEN2A | Medullary thyroid carcinoma + pheochromocytoma + hyperparathyroidism |
