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.

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.
  • 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.
    • Nobnail morphology (free surface larger than basement membrane surface).[3]

Ovarian surface vs. mesothelium:


Specific benign diagnoses

Endometriosis

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]

Pregnancy luteoma

General

  • Tumour of pregnancy.
  • Benign.
  • Regress after pregnancy; thus, conservative management.[8]

Clinical:

  • Increased serum testosterone.[9]

Gross

  • Solid.
  • Yellow.

Images:

Microscopic

Features:

  • Sheets of cells.
  • Cells with eosinophilic cytoplasm, round nuclei and prominent nucleoli.
