title: Renal angiomyolipoma: two varieties.
abstract: Two cases of symptomatic renal angiomyolipoma are presented, and their distinctive clinical, radiologic, and histologic features are discussed. In the first case the scout film demonstrated radiolucency of the tumor which helped to distinguish it from carcinoma. In the second case, which was associated with tuberous sclerosis, the renal lesion was large and unifocal, and the local lymph nodal involvement with tumor raised the possibility of malignant transformation.
