Renal metastasis from primary hepatocellular carcinoma. A case report and review of the literature.

Secondary malignant tumors of the kidney are uncommon. These secondary tumors are usually the result of hematogenous spread from solid or hematologic malignancies. These tumors are almost always discovered at autopsy, with only 40 cases diagnosed prior to death reported in the literature. Primary tumors of the lung, breast and gastrointestinal tract are the most common sources of renal metastases. The occurrence of a renal secondary from a primary hepatocellular carcinoma is the subject of this presentation. To the best of our knowledge, such an occurrence has not been reported previously.
