The most frequent localization, features of appearance and development, possible complications, treatment of hemangiomas.
Hemangioma is a local, benign vasodilatation, a consequence of a violation of their development in the embryonic period, and not a genuine tumor, but sometimes adjacent tissues are involved in this process. In general, hemangiomas are isolated, much less often multiple.
The most frequent localization is hemangiomas
- Most often, hemangiomas are located on the scalp, with the appearance of painless pinkish-red spots with distinct borders.
- In cases where the hemangioma is deeper (in the subcutaneous fatty tissue), it has a bluish color (in the type of hematoma).
- Hemangiomas of internal organs (liver, kidneys, bodies of vertebrae, muscles, etc.) arise less frequently. They are detected by accident, during the examination on another occasion (during ultrasound, X-ray examination).
The emergence and development of hemangiomas
The origin of hemangiomas is unknown, but it is considered that inheritance plays a role, especially when it comes to congenital hemangiomas. Much less commonly found hemangiomas that appeared in adulthood, here the influence of solar insolation is of particular importance.
It is believed that there is a certain developmental cycle in hemangiomas (it can last many years), but it is not always possible to trace it. Hemangiomas may suddenly appear, increase in size, and also disappear on their own. For this reason, in a childhood, as a rule, hemangiomas do not operate, as they may disappear themselves until the period of puberty.
Clinical manifestations and possible complications of hemangiomas
Hemangiomas are not prone to zzlokachestvlenie, they are painless and mainly concerned as a cosmetic defect. In some cases, when enlarged, they can interfere with the normal functioning of adjacent adjacent tissues and organs, such as hemangiomas, located in the century.
Sometimes, when damage to the skin of the hemangiomas, it may be their infection, increased bleeding (especially with disturbance of blood clotting). In case of damage to the internal organs hemangiomas (eg, road traffic injury), internal bleeding may occur, which will require immediate surgical intervention.
Appearing complications become a precondition for surgical treatment: bleeding, infected, inflamed, thrombophilic, ulcer and rapidly growing (doubling the size in one week) of hemangiomas. They are also subject to prompt treatment in the shortest time after the detection of hemangiomas, localized on the mucous membranes, in the region of the anus and external genital organs.
Treatment for hemangiomas
At present, many methods of treating hemangiomas without surgical intervention have been developed: laser deodorization, cryodestruction, radiotherapy, microwave therapy (ultrahigh frequency effects), hormonal therapy, and others. In each case, the doctor chooses the most appropriate treatment method.
Hemangiomas of the internal organs are treated operatively only in those cases where there is a risk of circulatory disturbance in adjacent hemangiomas (through compression).
