Multiple endocrine neoplasia, abbreviated MEN, refers to collection of different genetic abnormalities that lead to endocrine neoplasms.
Simple
MEN 1
Memory device: 3 Ps.
Note:
‡ May be mislabeled as parathyroid hyperplasia.[2]
MEN 2A (II)
- Parathyroid adenoma.
- Medullary thyroid carcinoma (usually preceded by C-cell hyperplasia[3]).
- Pheochromocytoma.
Notes - memory device:
- Both MEN 1 and MEN 2A have parathyroid adenomas.
- Each has additional neoplasms below and above the diaphragm.
MEN 2B (III)
- Neuromas/ganglioneuromas.
- Medullary thyroid carcinoma (usually preceded by C cell hyperplasia[3]).
- Pheochromocytoma.
Details
MEN 1
Gene:
- MEN1.[1]
Characteristics:[3]
- Endocrine tumours usually lead to most of the morbidity.
- Usually arise in the duodenum.
- May present as Zollinger-Ellison syndrome - triad of pancreatic gastrinoma, gastric hypersecretion, small bowel peptic ulcers.[4]
- Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) has been described in the context of multiple endocrine neoplasia 1.[5]
MEN 2A
Gene:
- RET.[6]
Characteristics:[3]
- Medullary thyroid carcinoma - in almost 100%.
Treatment:
- Patients are advised to have prophylactic thyroidectomy.
Images:
Trivia:
- In MEN 2A and 2B the RET gene is abnormally activated. In Hirschsprung disease, it is inactivated.[3]
MEN 2B
Gene:
- RET.[7]
Characteristics:
- Marfanoid habitus.[8]
- Neuromas.
- Multiple ganglioneuromas (ganglioneuromatosis) of the alimentary tract.[7][9]
- Ganglion cells + spindle cells.[10]
Treatment:
- Patients are advised to have prophylactic thyroidectomy.
