Renal angiomyolipoma

Renal angiomyolipomas (AML) are the most common benign tumor found in the kidney. They are composed of vascular cells, immature smooth muscle cells and fat cells. While they are classed as benign they can still affect the function of the kidney depending on their size and location. In most cases AML occur as a single mass, but rarely it can affect both kidneys and it is possible to have more than one at a time.Angiomyolipoma is commonly associated with other diseases such as tuberous sclerosis (genetic disease) and lymphangioleiomyomatosis(a rare lung disease).
