Bilateral renal angiomyolipoma: involvement of the contralateral kidney after 25 years--an unusual case.
The diagnosis of renal angiomyolipoma often poses problems, both clinically and pathohistologically. With the increasing refinement of imaging techniques it is becoming potentially possible to recognize these benign neoplasms by means of ultrasound, computed tomography and magnetic resonance imaging. Electron microscopy and histochemical methods are often necessary for the correct pathological diagnosis. The problems involved are presented on the basis of the case history of a patient who suffered from renal angiomyolipoma in both kidneys with an interval of 25 years. The first tumor was diagnosed histologically as a liposarcoma 25 years ago.
