Breast carcinoma is the most common malignant tumor in the female. A vast majority of the cases present metastasis at the time of diagnosis. A case of breast carcinoma metastatic to the kidney is described to emphasize that in the presence of a renal mass, a secondary or metastatic tumor should be suspected. The literature is briefly reviewed. We report on the diagnosis and treatment of an expanding left renal mass in a female patient with a previous history of multiorgan tumors (ovarian, breast and small bowel) or different histological types that had been diagnosed and treated at different periods. Following radical nephrectomy, analysis of the surgical specimen disclosed a metastatic tumor from breast carcinoma. No subsequent treatment was required and the patient is well 6 months postoperatively. Metastasis from a primary tumor must be suspected in patients with a previous history of tumor presenting with a renal mass. Renal metastasis presents in the advanced stages of tumor dissemination. Treatment depends on patient general condition and the stage of the primary and metastatic tumors.
