An ovarian metastasis (also ovary with metastatic disease and metastatic ovarian disease) is cancer in the ovary that arose elsewhere and spread to the ovary.
Generally
- Mostly Muellerian origin (uterus, fallopian tube) or pelvic peritoneum.
Common extramuellerian metastatic tumours:
- Breast.
- Gastrointestinal (GI) tract.
- Pseudomyxoma peritonei, usu. appendiceal origin.
- Krukenberg tumour = signet ring cell cancer with mucin production of GI origin.
Gross
Features favouring metastatic mucinous carcinoma (from the GI tract) over primary ovarian mucinous carcinoma:[1]
- Bilaterality - both ovaries involved.
- Small unilateral tumour size.
- <10 cm suggests metastasis.
- >13 cm = ovarian primary.
Microscopic
Features:
- Predominantly surface involvement and nodular at low power.
- +/-Signet ring cells (suggestive of GI or breast primary).
- Lymphovascular invasion.

IHC
Ovarian tumours:
- Dipeptidase 1 (DPEP1) +ve.[2]
- CK7 +ve.
