Prolactinoma synonyms

A prolactinoma is a benign, hormone-secreting tumor of the pituitary gland, most commonly referred to by this specific clinical name. While you may encounter terms like "prolactin-secreting pituitary adenoma" or "lactotroph adenoma" in medical literature, prolactinoma remains the standardized term used by clinicians, researchers, and global health organizations to describe this condition.

What are the common synonyms for prolactinoma?

In medical records and older literature, you may see a prolactinoma referred to by various names based on its cell origin or functional activity. Because it is a growth originating from the lactotroph cells of the anterior pituitary, it is scientifically classified as a lactotroph adenoma. Common synonyms include:

• Prolactin-secreting pituitary adenoma


• Lactotroph adenoma


• Prolactin-producing pituitary tumor


• Hyperprolactinemia-associated pituitary adenoma (descriptive of the secondary hormonal effect)

Why does this condition have multiple names?

The naming conventions for a prolactinoma reflect a transition from historical, symptom-based descriptions to modern, cell-specific classifications. Before modern immunohistochemistry allowed doctors to identify specific hormone production, these growths were simply called "pituitary adenomas." As our understanding of endocrine function evolved, the term prolactinoma became the preferred shorthand because it directly identifies the specific hormone being overproduced.

How is prolactinoma classified in medical systems?

Standardized coding systems use specific nomenclature to ensure accurate diagnosis and treatment tracking for prolactinoma:

1. ICD-10/11: Typically coded under benign neoplasms of the pituitary gland (e.g., D35.2).


2. Orphanet: Listed as ORPHA:756 (Prolactinoma).


3. OMIM: Frequently discussed under entries related to pituitary tumors and Multiple Endocrine Neoplasia (MEN) syndromes.

Which term should patients use?

When communicating with your healthcare team, prolactinoma is the most widely recognized and precise term. Using this name ensures clarity across endocrinology, neurosurgery, and radiology departments. The 58 community members on DiseaseMaps.org who live with this condition also utilize "prolactinoma" as the primary term to share their experiences and support one another.

Next steps

• Consult an endocrinologist to discuss your specific hormone levels and imaging results.


• Request your pathology reports to see if your prolactinoma is classified as microadenoma (under 10mm) or macroadenoma (10mm or larger).


• Connect with others on DiseaseMaps.org to share experiences and coping strategies.
