symptomatic tumor (87.5%), absence of histological evidence of benign tumor
preoperatively because the fat component does not always eliminate renal cancer.
For the eighth patient, monitoring of clinical and laboratory evolution of the
tumor was indicated, but was unfortunately lost sight.
The pathological analysis showed triphasic AML in all cases. In two patients
the pathology report showed the presence of necrotic alterations (Comment No. 3
and 4), one even had the invasion of the capsule and perirenal fat. Athird patient
had an infiltration of the right renal vein (Comment No. 5). In another patient (case
No. 2), histological study had revealed asecond tumor associated with AML in the
same kidney and corresponded to the renal cell carcinoma.
AML is a rare benign tumor that usually occurs in women. The presumed
diagnosis based on CT, the positive diagnosis is histological. Its management should
be conservative, to preserve the renal function. But the use of total nephrectomy is
sometimes unavoidable. The therapeutic prospects of AML are mini-ablative surgery
(cryoablation and radiofrequency) and medical treatment with rapamycin.
