The ovary has a wealth of pathology. It has benign tumours and malignant ones. It is a significant part of gynecologic pathology.

Normal ovary

  • Corpora albicans - pale/white body with lobulated contour.
    • Involuted corpus luteum.
    • Not seen pre-pubertal.
    • Number increase with age.
  • Ovarian follicles.
  • Stroma - hyperchromatic - spindle morphology, whorling.
    • If the cells have a round morphology... think about endometriosis.

  • Corpus albicans. (WC)

Cysts - overview

General

  • Very common.

Most common:

  • Serous cystadenoma.
    • Usually uniloculated.
    • Morphology: ciliated, columnar.
  • Mucinous cystadenoma.
    • Usually multiloculated.[1]
      • Memory device: multiloculated = mucinous.
  • Endometrioma (see endometriosis).
  • Simple cyst.
  • Corpus luteum cyst.
  • Cancerous cyst (see ovarian cancer).

Notes:

  • Epithelium is often lost in processing - may make interpretation challenging
  • Ovarian surface epithelium (previously call germinal epithelium) - covers the ovary
    • Cuboidal/flat epithelium.[2]
    • Has ovarian stroma underneath.
    • Hobnail morphology (free surface larger than basement membrane surface).[3]

Specific benign diagnoses

Endometriosis

Main article: Endometriosis

Corpus luteum cyst

General

  • Normal in childbearing age women.

Gross

  • Classically yellow.

Microscopic

Features:

  • Pseudocyst lined by stratified, pale staining (luteinized) cells.
  • +/-Hemorrhagic centre.

Benign mesothelial inclusion cyst

General

  • May be found incidentally, e.g. during C-section.

Epidemiology:

  • Associated with previous surgery.

Gross

  • May mimic mucinous tumour - to unexperienced.[5]
  • Thin-wall.[6]
  • Clear/translucent fluid.

Microscopic

Features:

  • Benign mesothelium.
    • Single layer of squamoid or cuboid mesothelial cells.[6]
