The mnemonic
3 Ps
What each word stands for
- ParathyroidHyperplasia or adenomas of the parathyroids
- PituitaryPituitary adenomas such as prolactinoma
- PancreasPancreatic endocrine tumours such as gastrinoma and insulinoma
Why it matters clinically
Parathyroid disease is usually the first manifestation, so multiple-gland disease should prompt screening.
Where it stops being reliable
The gene is MEN1 (menin), not RET, and the mnemonic gives no detail on tumour behaviour.
