A 77-year-old man was diagnosed to have diabetes. He was hospitalized for appetite loss, weight loss (6 kg/3 months) and right femoral pain. An abnormal shadow was noted on chest X-P. On admission, he was alert and there were no abnormal physical findings except limitation in the range of motion in the right lower extremity. His femoral pain was treated by a non-steroid anti-inflammatory drug (NSAID). Right femoral bone biopsy revealed angiosarcoma and staining for factor VIII, with negative staining for epithelial membrane antigen on enzyme assay. Therefore, he received systemic administration of recombinant interleukin-2 (rIL-2). rIL-2 was administered intravenously twice daily at a dose of 40 x 10(4) JRU. The total dosage of rIL-2 amounted to 1200 x 10(4) JRU, but renal failure deteriorated and he died on the 50th hospital day of his second admission. Combination of rIL-2 and NSAID may cause progression of nephropathy.
