ABSTRACT = {We report a case of renal epithelioid angiomyolipoma that 
arose in association with a classic angiomyolipoma in a 
54-year-old Japanese man without tuberous sclerosis. 
Histologically, the tumor was composed of polygonal 
cells exhibiting diffuse hemorrhage, multifocal necroses, 
and vascular invasion. Immunohistochemical staining 
was positive for melanoma specifi c antibody and focally 
positive for smooth muscle actin. On the basis of a 
review of the literature, we suggest that large epithelioid 
angiomyolipoma may have malignant potential and 
therefore requires close follow up.},
