title: Renal angiomyolipoma with extrarenal involvement--in vascular, lymph-node and perirenal tissue. Reports of four cases.
abstract: Extrarenal involvement was found in four cases of renal angiomyolipoma. In one case the wall of the inferior right bronchial artery was infiltrated, lymph nodes were involved in two cases and the perirenal fat in one case. Extrarenal extension does not seem to alter the prognosis of renal angiomyolipoma. Expectant treatment of this rare condition therefore appears to be warranted.
