Krukenberg tumors are uncommon metastatic neoplasms of the ovary with a prominent component of signet ring cells. The occurrence of a Krukenberg tumor in young individuals is rare, with only few cases reported in the second decade of life. The authors describe a case of this tumor diagnosed in an 11-yearold girl, characterized by massive metastatic spread, lack of tumor response and rapidly fatal clinical course. To the best of our knowledge, this is the youngest patient with Krukenberg tumor reported to date.
