The ovary has a wealth of pathology. It has benign tumours and malignant ones.

Normal

  • Corpora albicans - pale/white body with lobulated contour.
  • Ovarian follicles.
  • Stroma - hyperchromatic - spindle morphology, whorling.
    • If the cells have a round morphology... think about endometriosis.

Cysts

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:

Endometriosis

Ovarian tumours
