Abstract

We report a case of a metastatic renal tumor secondary to breast cancer 9 years postmastectomy. This is the first case report of solitary renal metastasis from breast cancer with no other evidence of metastasis. A 47-year-old woman underwent a modified radical mastectomy and 6 cycles of CEF chemotherapy(Cyclophosphamide, Epirubicin, 5-FU) for cancer of the left breast. She was followed closely, but no recurrence or metastases were detected on either a physical or radiological examination. 9 years later, on a routine follow-up examination for metastatic breast cancer, abdomen ultrasound revealed a solid mass(4cm in diameter) in the upper portion of the right kidney. Computed tomography(CT) was used to further evaluate the solitary renal mass, which had become moderately enhanced. No regional lymph node, visceral or pulmonary metastases were found. A radionuclide bone scan confirmed no bony involvement. A laparoscopic radical nephrectomy was performed for a right renal tumor. The histopathological features were identical to those for cancer of the right breast. The patient was treated with adjuvant combination chemotherapy(docetaxel and adriamycin), and is still alive 9 months after a right radical nephrectomy, with no evidence of recurrence.
