[Liver metastasis with portal vein tumor thrombosis as a late recurrence of chromophobe renal cell carcinoma].

ABSTRACT

We report a case of liver metastasis with portal vein tumor thrombosis from chromophobe renal cell carcinoma (RCC). A 62-year-old man was noted to have a wedge-shaped low density area in the liver by computed tomography thirteen years after radical nephrectomy. Hepatic arterioportal shunt was suspected because liver biopsy did not show malignancy. Several months later, the patient showed aggravation of liver function which did not improve regardless of anticoagulant therapy. Recurrent liver biopsy revealed metastatic RCC. Autopsy showed portal vein tumor thrombus from RCC in the liver.
