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.

Can hemangiomas be left untreated?

Hemangiomas on the head and face, and those around the eyes, tend to invade the eyeballs or cause complications such as glaucoma. Hemangiomas in the parotid gland area can compress or damage the facial nerve, leading to facial paralysis. Nasal hemangiomas may block the nasal passages, causing deformities of the nostrils. Lip hemangiomas, due to friction from sucking or eating, are prone to rupture causing deformities of the lip; ear hemangiomas, because of poor blood circulation, are prone to infection after rupture. Hemangiomas on the limbs and body, due to the rapid growth of some, can invade muscle tissue, bones, or joints, causing local pain and, in severe cases, joint deformities and other functional symptoms. Therefore, it is necessary to treat hemangiomas.

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.

What should be done about infantile hemangiomas?

If an infant has a hemangioma, it is first necessary to assess the location and size of the hemangioma. Currently, the main treatments for hemangioma include: Firstly, oral medications such as Xin De An, which is commonly used for cardiovascular issues, can gradually reduce the size of the hemangioma. Although it is an oral medication, it is essential to conduct electrocardiograph and echocardiogram examinations before taking the medication, and the treatment should be carried out under the guidance of a hospital doctor, followed by regular observation. Secondly, topical application of certain eye drops may gradually reduce smaller hemangiomas. Thirdly, surgical treatment is used for particularly large hemangiomas to completely eliminate them. Another method is to treat older children with laser or plasma therapy; this is generally performed when the child is older, and the local treatment is quite effective.

How are hemangiomas formed?

The etiology of hemangioma is unknown. Studies have shown that the use of progesterone during pregnancy, undergoing chorionic villus sampling, hypertensive disorders during pregnancy, and low birth weight at the time of birth may be related to the formation of hemangiomas. It is believed that hemangiomas are a result of minor misconfigurations in the control gene segments during the embryonic development process, particularly during the early stages of vascular tissue differentiation. This leads to abnormal tissue differentiation at specific sites, eventually developing into hemangiomas. During the early months of embryonic development, from eight to twelve months, mechanical damage to embryonic tissue and local bleeding can cause some hematopoietic stem cells to be distributed among other embryonic cells, some of which differentiate into vessel-like tissues and ultimately form hemangiomas.
