Abstract
|
|
|
|
Angiomyolipoma is a benign tumor that is composed of adipose tissue, blood vessels and smooth muscle. The kidney is the most common location of this tumor. In the larynx, angiomyolipoma has been rarely reported in the literature. We describe the patient of 64-year-old male with an angiomyolipoma arising from the vallecula. The tumor had a smooth surface with numerous small vessels and showed heterogeneous contrast enhancement on CT. The tumor was not adhesive to surrounding tissue and was completely removed by laryngomicrosurgery with CO2 laser. Microscopically, the tumor is composed of mature adipose tissue, tortuous thick walled blood vessels and thick bundles of smooth muscle.
