Abstract
- Angiomyolipoma is a benign neoplasm composed of fat, smooth muscles and blood vessels. We report a case of a 64-year-old man with a renal angiomyolipoma which rapidly extended to perinephric space. He had been diagnosed of having a small renal angiomyolipoma, and seven years later, a large perinephric mass was newly detected. Right nephrectomy with mass excision revealed an exophytic mass in the lower pole of right kidney which extended to perinephric space. A histological examination showed large angiomyolipomatosis. Clinicians who follow the renal angiomyolipoma should be aware of the unusual perinephric progression.
