Pathophysiology

• Tumor classification according to ability to secrete hormones
  • Nonsecretory pituitary adenomas
    • Nonfunctioning tumors account for 15–45% of all pituitary adenomas.
    • Gonadotroph adenomas
    • Null cell adenomas
    • Plurihormonal adenomas
    • Silent somatotroph and corticotroph adenomas
  • Secretory pituitary adenomas: hormone secretion → hyperpituitarism
    • Most exclusively proliferate in only one type of endocrine cell and therefore secrete only one pituitary hormone.

Tip

Prolactinomas are the most common pituitary adenomas.
