Hemangiomas fade when pressed and quickly redden upon release, suggesting the presence of a hemangioma. Hemangiomas are benign tumors that may grow as the body grows and can be observed over time without immediate treatment. For cosmetic reasons, treatment options include cryotherapy, laser treatment, or injection of a sclerosing agent. For smaller hemangiomas, laser treatment is recommended due to its relatively minimal harm to the body.

Is a hemangioma a tumor?

Hemangiomas are formed by the proliferation of vascular endothelial cells during embryonic development and are commonly seen in congenital benign tumors or vascular malformations of the skin and soft tissues, mostly observed at birth or shortly after birth. The residual embryonic vascular endothelial cells, active endothelial-like embryonic buds invade adjacent tissues, forming endothelial-like cords, which after canalization connect with existing blood vessels to form hemangiomas. The blood vessels within the tumor form a separate system, not connected to surrounding blood vessels. Hemangiomas can occur throughout the body; those occurring in the oral and maxillofacial regions account for 60% of all hemangiomas, followed by 25% in the trunk and 15% in the limbs. Therefore, some hemangiomas are congenital benign tumors, while others are caused by vascular malformations.

How to treat nasal hemorrhagic angioma?

There are many causes of nosebleeds. If the bleeding is caused by a hemangioma, surgery is generally required. After the surgical removal of the hemangioma, hemostatic treatment can usually be carried out. If the hemangioma is particularly small, some patients may also consider nasal packing for compression hemostasis. After compression by packing, some patients may have the hemangioma occluded and then stop bleeding. However, regular follow-ups are still needed in this situation, as some patients may experience recurrent conditions, and regular nasal endoscopy checks are required to observe any changes in the nasal and sinus conditions. Additionally, routine blood tests and coagulation function tests should be conducted to rule out any blood diseases.

Is a hemangioma in the nose dangerous?

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.

Causes and Treatment of Infantile Hemangiomas

Infantile hemangiomas are usually caused by congenital factors, and the pathogenesis and specific causes of hemangiomas are not very clear at the moment. Since there is a certain possibility that infantile hemangiomas can heal on their own, if the hemangioma's location is not very noticeable and not particularly significant, it is advisable to initially observe it. If the hemangioma has not healed on its own by the time the child turns five, consideration can be given to treat it with sclerosing injections or through surgery. If the hemangioma is located in an internal organ and does not severely affect the child's health under normal circumstances, it could still be quite dangerous if it bursts. Therefore, parents should give it enough attention.

Can hemangiomas resolve on their own?

Infantile hemangiomas may regress spontaneously in some cases, so for lesions that are relatively stable in growth, temporary observation without treatment is recommended, especially avoiding surgical treatment. Radiation therapy, which may cause secondary developmental deformities, is not recommended. Medicinal treatment mainly involves the use of steroids and interferons. Steroid therapy is the most common drug treatment for hemangiomas, with the first reports of using steroids for hemangiomas appearing in the mid to late 1960s. Since then, prednisone and prednisolone have been considered first-line drugs for treating life-threatening or vision-threatening hemangiomas. The effective rate of steroid treatment for hemangiomas varies from 30% to 90%. Therefore, we suggest that since infantile hemangiomas can regress on their own, lesions that are stable in growth can be temporarily observed.
