A Giant Intra Abdominal Mass Mimicking Renal Cell Carcinoma: A Rare Presentation of Renal Angiomyolipoma.
Angiomyolipoma (AML) is a benign tumor commonly found in kidney than extra renal sites. Most of the small renal angiomyolipomas are diagnosed incidentally on ultrasound and other imaging studies. Some renal AMLs present clinically when become very big, giant renal angiomyolipoma. Although almost all cases are benign, a relatively rare variant of epitheloid angiomyolipoma has got malignant potential and can even metastasize. Ultrasonography, CT and MRI scan are usually used for diagnosis of angiomyolipoma with high level of accuracy; even though some lesions may be confused as renal cell carcinoma on imaging studies. Here, a 48 year old man presented with a large intra-abdominal mass preoperatively diagnosed as a case of right renal cell carcinoma and radical nephrectomy was performed. Histopathology revealed epitheloid angiomyolipoma (EAML).
