Angiomyolipoma with caval extension and regional nodal involvement: Aggressive behaviour or just rare natural history? Case report and review of literature

Abstract

Renal angiomyolipoma (AML) is predominantly a non-aggressive benign tumour. Cases of more aggressive AMLs are present in the literature. We present 2 cases of aggressive AML behaviour. The first case is an AML with vascular extension in a young female and the second case is of AML found in regional lymph nodes in a female with a left renal AML and renal cell carcinoma.
