Non-functioning pituitary adenoma

ORPHA:91349Disease

Also called NFPA

What it is

A rare pituitary tumor originating from normally hormone-producing cells of the adenohypophysis, characterized by a sellar or extrasellar mass manifesting with clinical signs secondary to mass effect, but without evidence for hormonal hypersecretion. Typical manifestations are visual disturbances, headaches, cranial nerve dysfunction, and hypopituitarism but the mass may also be discovered incidentally.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

Genes reported in subtypes

AIPMEN1

Orphanet records these genes on 2 more specific entries under this disorder, not on this entry itself:

A well-studied disease is usually split into subtypes, and the gene is curated on whichever one the evidence belongs to. Open a subtype to see which gene goes with it.

ICD-10 codes

D35.2filed under a broader ICD-10 category — shared with 10 other rare diseases

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
