Nasal hemangiomas are primarily caused by congenital or acquired vascular malformations. The risks associated with them include the following points: First, the vessel walls of hemangiomas are imperfect and prone to bleeding. Excessive bleeding can lead to hemorrhagic shock. Furthermore, significant bleeding can cause blood to flow back into the respiratory tract, leading to coughing fits and even the risk of suffocation. Second, although hemangiomas are benign in nature, a few of them possess the biological characteristic of expansive growth. This characteristic can damage surrounding tissues, such as destroying the wall of the vessel and the structure of the tumor, thereby exhibiting malignant-like biological behavior. Therefore, active treatment is necessary.
