Overview
Prolactinoma may occur as part of a hereditary disorder called multiple endocrine neoplasia type 1 (MEN 1). A minority of prolactinomas are associated with Carney complex, McCune-Albright Syndrome, MEN like syndrome (CKDN1B loss of function).[1]
Pathophysiology
Associated Diseases
Prolactinoma may occur as part of a hereditary disorder called multiple endocrine neoplasia type 1 (MEN 1). A minority of prolactinomas are associated with:[1]
- Multiple endocrine neoplasia type I (MEN I)
- Carney complex
- McCune-Albright Syndrome
- MEN like syndrome (CKDN1B loss of function)
Familial pituitary adenomas
A pituitary adenoma may be part of a familial syndrome:[2]
| Syndrome | Gene | Notes |
|---|---|---|
| Multiple endocrine neoplasia I | MEN1 | characterized by the 3 Ps: pituitary adenoma, parathyroid adenoma, pancreatic neuroendocrine tumor |
| MEN-1-like syndrome | CDKN1B[3] | also known as Multiple endocrine neoplasia IV[3] |
| Carney syndrome | PRKAR1A | other findings (mnemonic NAME): nevi, atrial myxoma, myxoid neurofibroma, ephelides (freckles) |
| Isolated pituitary adenoma[4] | AIP | classically growth hormone-producing adenoma - leads to acromegaly |
Microscopic Pathology
Features of prolactinoma include:
Notes:
- Smears very well
Stains
- Reticulin - loss of reticulin between tumor cells
