A<unk>  is a relatively rare form of lung tumours. These tumours can form in the lower respiratory tract tissue of the bronchi, trachea and other lung tissue. They may also be derived from blood vessels. These tumors typically form from the smooth muscle tissue lining the bronchi. They grow as a solitary tumor attaching themselves to the sides of the bronchi.
