[Case of double primary carcinoma of the lung and ureter].

A 73-year-old man visited our hospital complaining of chest distress in September 1979. A chest X-ray film showed a tumor shadow in the left lung and left inferior lobectomy was performed. The tumor measured 50 X 40 X 30 mm; it was diagnosed as large cell carcinoma. In November 1980 the patient suddenly noticed macroscopic hematuria although there had been no microscopic hematuria at his first visit. Ultrasound-guided percutaneous pyelography confirmed complete obstruction of the left ureter and he underwent left ureteronephrectomy. The papillary tumor, measuring 23 cm, was diagnosed as transitional cell carcinoma.
