[Angiomyolipoma of the kidney: a case of spontaneous rupture]

After reporting the general features of renal angiomyolipoma (AML), either isolated or associated to other conditions (Bourneville sclerosis, Wunderlich's syndrome), the Authors discuss a case complicated by perirenal spontaneous hematoma, undergone emergency operation (simple nephrectomy). At a 3 year follow-up the patient is in good general and local conditions (negative TC, normal renal function, preexistent hypertension disappeared). Literature is reviewed and some considerations about diagnosis and surgical tactics are reported.
