Krukenberg tumor (carcinoma mucocellulare)

• metastatic ovarian adenocarcinoma from different primary tumor sites
• gastric carcinoma is the commonest primary tumor (~50% of Krukenberg tumors)
• T4 colonic adenocarcinoma have potential for transcoelomic spread to the ovaries
• discrimination between primary and metastatic ovarian tumors is important

Learning points

• if an ovarian "primary" tumor is reported as mucinous or adenocarcinoma: think could this be a Krukenberg tumor until proven otherwise
• iron deficiency anemia in post-menopausal women: think - right-sided colon cancer
