A Krukenberg tumor refers to a malignancy in the ovary that metastasized from a primary site, classically the gastrointestinal tract, although it can arise in other tissues such as the breast.[1] Gastric adenocarcinoma, especially at the pylorus, is the most common source.[2] Krukenberg tumors are often (over 80%)[2] found in both ovaries, consistent with its metastatic nature.[2]
