The ovary has a wealth of pathology. It has benign tumours and malignant ones.
Normal
- 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
General:
- Very common.
Most common:
- Serous cystadenoma.
- Usually uniloculated.
- Morphology: ciliated, columnar.
- Mucinous cystadenoma.
- Usually multiloculated.[1]
- Memory device: multiloculated = mucinous.
- Usually multiloculated.[1]
- 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
Ovarian surface vs. mesothelium:

Endometriosis
Main article: Endometriosis
Ovarian tumours
Main article: Ovarian tumours
For a very brief overview of gynecologic tumours see: Gynecologic pathology.
Benign mesothelial inclusion cyst
Epidemiology
- Assoc. with previous surgery.
- May be found incidentally, e.g. during C-section.
Gross
Microscopic
Features:
- Benign mesothelium.
- Single layer of squamoid or cuboid mesothelial cells.[5]
IHC
- CK +ve, calretinin +ve.[5]
Pregnancy luteoma
General
- Tumour of pregnancy.
- Benign.
- Regress after pregnancy; thus, conservative management.[6]
Clinical:
- Increased serum testosterone.[7]
Gross
- Solid.
- Yellow.
Microscopic
Features:
- Sheets of cells.
- Cells with eosinophilic cytoplasm, round nuclei and prominent nucleoli.
