[Diagnostic and therapeutic problems in angiolipoleiomyoma]

6 cases of angiolipoleiomyoma of the kidney operated in the last 10 years are discussed. New diagnostic possibilities and also, the problems of providing an accurate preoperative diagnosis are mentioned. Usually therapeutic steps depend on whether the tumor ist presenting in combination with tuberous sclerosis or wether it is isolated. Radical surgery is more frequent and justifiable when the tumor is isolated, than in patients with tuberous sclerosis, where the therapy should be more conservative.
