Introduction
  • An estrogen-dependent hyperplasia affecting mainly postmenopausal women
    • incidence peaks between ages 50 and 60
  • Risk factors include
    • increased estrogen exposure

      • late menopause (after age 52)
      • polycystic ovarian syndrome

      • anovulation
    • cancer syndromes
      • hereditary nonpolyposis colon cancer
  • 3 classes of hyperplasia severity
    • simple
      • ↑ number of glands with no crowding
    • complex
      • ↑ number of branching glands with crowding
    • atypical
      • ↑ number of atypical glands with crowding
      • highest risk of progression to endometrial cancer
Presentation
  • Symptoms
    • abnormal uterine bleeding
    • post-menopausal bleeding
Evaluation
  • Tissue biopsy
    • gold standard
Treatment
  • Pharmacologic
    • progesterone
      • indications
        • simple or complex hyperplasia
      • used to reverse hyperplastic process
  • Surgical
