[Breast metastasis as the initial clinical symptom of renal adenocarcinoma]

Renal adenocarcinoma shows an unpredictable clinical course. At autopsy, metastases are present in as many as 95 percent of patients with renal adenocarcinoma. The percentage of metastases from renal adenocarcinoma is greater than would be expected from the frequency of this carcinoma among all carcinomas. The breast is an exceptional site of metastasis, that is not described in literature. In the present report the metastasis in the breast represented the early symptom of renal adenocarcinoma.
