| Explanation | [[Explanation::A Krukenberg tumor refers to a tumor in the ovary that has metastasized from a primary site, classically the gastrointestinal tract, although it can develop in any other tissue. Krukenberg tumors are characterized by epithelial and stromal masses, whose epithelial component contains mucin-laden signet ring cells with hyperchromatic nuclei and eosinophilic granular cytoplasm. They usually appears as bilateral tumors with signs of lymphatic obstruction. Krukenberg tumors are often diagnosed in patients in their fifth decade.
