[Malignant lymphoma from left renal capsule: report of case].

A 59-year-old woman was admitted to our clinic with the complaint of left flank pain. Excretory urogram showed left hydronephrosis. Computed tomographic (CT) scan and renal angiography showed a left renal capsular tumor. Histological specimen obtained by a sure cut needle suggested malignant lymphoma. She was treated with a combined treatment of 8 MHz radiofrequency hyperthermia in a total of 10 sessions and 5,440 rads irradiation for 5 weeks. After the treatment, CT scan showed 92% tumor regression. After that, a recurrent tumor in left shoulder muscle became manifest. She received combination chemotherapy with 3 courses of ABEP regimen (aclacinomycin, cytosine arabinoside, etoposide, prednisolone) and 7 courses of ACOPE regimen (adriamycin, cyclophosphamide, vincristine, prednisolone, etoposide) and complete remission was obtained.
