Abstract
- Renal angiomylipomas are uncommon benign neoplasms composed of mature fat tissue, thick-walled blood vessels and smooth muscle in varying proportions, which can be commonly diagnosed by those unique fat nature in abdominal ultrasonography and abdominal CT scan. Renal angiomyolipomas without demonstrable fat component are rarely reported which is difficult to differentiate from renal cell carcinoma. We report a case of renal angiomyolipoma without demonstrable fat component which was proven to positive HMB-45 stain after partial nephrectomy.
