Abstract

Angiomyolipomas (AMLs) are benign tumours characterized by
fat, smooth muscle and vascular components. Epithelioid AML
is a recognized variant of AML that is comprised of epithelioid
smooth muscle cells. We present a case of a 41-year-old male who
presented with light-headedness, dizziness, right-sided abdominal
pain and, on subsequent computed tomography, was found to
have an enormous right kidney mass characteristic of an AML.
The patient underwent preoperative selective arterial embolization
followed by a right radical nephrectomy. The pathology revealed a
36-cm AML with focal epithelioid features. Although uncommon,
AMLs can present as enormous retroperitoneal masses.
