[Metastatic renal tumor of malignant salignant salivary-gland-like tumor of the lung: A case report].

A 17-year-old woman was admitted to our hospital for the investigation of asymptomatic gross hematuria. Twenty nine months ago, she had received the right lower lobectomy because of the malignant salivary gland type mixed tumor of the bronchus. The intravenous pyelography and the right retrograde pyelography showed the irregular wall of the right renal pelvis. The computerized tomography showed a hypodense tumor which occupied the lower half of the right kidney. Cystoscopy showed bleeding from the right ureteral orifice. Chest X-ray revealed multiple lung metastases at the first examination, but right nephrectomy was performed because gross hematuria continued. The tumor thrombus, which spreaded into vena cava, was removed. The pathological diagnosis was the metastatic renal tumor of malignant salivary gland type mixed tumor. The patient died 102 days postoperatively.
