Multiple endocrine neoplasia, abbreviated MEN, refers to collection of different genetic abnormalities that lead to endocrine neoplasms.
Simple
MEN 1
- Parathyroid adenoma.[1]
- Pancreatic neuroendocrine tumours.
- Pituitary adenoma.
Memory device: 3 Ps.
MEN 2A/2B (II/III)
- Parathyroid adenoma.
- Medullary thyroid carcinoma (usu. preceded by C cell hyperplasia[2]).
- Pheochromocytoma.
Notes:
- BOTH have parathyroid adenoma.
- EACH has one below and one above the diaphragm.
Details
MEN 1
Characteristics:[2]
- Endocrine tumours usu. lead to most of the morbidity.
- Usu. arise in the duodenum.
- Zollinger-Ellison syndrome is common.
- Usu. arise in the duodenum.
MEN 2A
Characteristics:[2]
- Medullary thyroid carcinoma - in almost 100%.
Images:
Trivia:
- In MEN 2A and 2B the RET gene is abnormally activated. In Hirschsprung disease, it is inactivated.[2]
MEN 2B
Characteristics:
- Marfanoid habitus.[3]
- Neuromas.
- Ganglioneuromatosis of the alimentary tract.[4][5]
- Extra large nerves in GI tract.
