Krukenberg tumors are ovarian metastases from different malignancies, most often originating from the gastrointestinal tract. However, in rare cases, other primary tumors, even with extra-abdominal location, might lead to the development of such lesions. Neither the mechanism of development, prognostic significance or therapeutic strategy are not clearly defined so far. It seems that these lesions are more frequently encountered in patients with BRCA1/2 mutations. Most often, Krukenberg tumors are bilateral lesions associated with ascites and with firm areas at the level of the ovarian surface. This paper aims to review existing data regarding Krukenberg tumors from breast cancer.
