Renal angiomyolipoma is a rare benign tudor composed of an intimate mixture of fat,
blood vessels, and smooth muscle.
But this tumor is often found in patients with tuberous sclerosis.
This tumor may also arise independently of this complex and occurs the incidence
higher in women when the tumor was not associated with tuberous sclerosis.
This tumor tend to arise multifocally and occasionally bilaterally.
We have reported a case of angiomyolipoma in 44 pears old woman.
Grossly, submitted specimen consists of a large kidney, measuring 17×12×8㎝ in
dimension and 950 gm in weight.
On cut section, there are three pseudolobulated yellowish tumor masses with massive
homorrhage.
Microscopically, sections from the main masses are composed of numerous fat cells,
blood vessels, and smooth muscle.
