Renal metastases are the most common malignant manifestation of the kidneys in autopsies. Common primary cancer sites are lung cancer, breast cancer, gastrointestinal cancer, malignant melanoma and lymphoma.
Metastases from lung cancer, breast cancer or colon cancer may present as single large lesions, a distinction to renal cell carcinoma may be difficult.
Fine needle biopsy is used to confirm the diagnosis, especially if a curative resection (with treatment of the primary tumor) is not intended.
Palliative nephrectomy is rarely necessary. Treatment is normally limited to chemotherapy and/or medical palliation of symptoms.
