[A case of renal malignant lymphoma]

Malignant lymphoma affects any organ of the body, but is rarely found in a urological organ. We found a case of renal malignant lymphoma. A 45-year-old male, who had been operated on for primary hepatic malignant lymphoma 9 months previously, was admitted to our clinic, complaining of high fever. X-ray and ultrasonographic examinations suggested a metastatic tumor in the right kidney. Right nephrectomy was performed, and pathohistological examination revealed primary hepatic malignant lymphoma in the right kidney.
