A 79-year-old male was admitted for macroscopic hematuria and right back pain. A mass shadow in the right lower lung fields had been present for three years previously with unconfirmed diagnosis. Excretory urogram, ultrasonogram and computed tomographic scan revealed bilateral renal tumors. Selective right renal arteriogram demonstrated a slightly hypervascular mass in the upper pole of the right kidney. Chemotherapy was not effective. Slow but definite malignant progression developed and the patient died two and a half years later. Autopsy finally revealed the adenoid cystic carcinoma of the right lung with bilateral renal metastases. The renal metastasis of this tumor is the first case in Japan to our knowledge.
