Types of hemangiomas
There are simple hemangioma originating fromthe smallest blood vessels - capillaries; cavernous hemangioma consisting of cavities filled with blood; Combined hemangioma, cavernous with subcutaneous and cutaneous capillary part; and mixed, consisting of not only blood vessels but also involving other tissues.
Simple hemangiomas are red orblue-purple color, are located superficially, clearly demarcated, affect the skin and a few millimeters of subcutaneous fat layer, growing mainly in the side.
The surface is smooth hemangiomas, at least - is uneven, sometimes slightly protruding above the skin. When pressed hemangioma blanch, but then again regain their color.
Cavernous hemangiomas are located under the skina limited education nodular, soft-elastic consistency and consist of different size cavities - caverns filled with blood. They appear in the form of tumor formation, coming from the subcutaneous fat layer, is covered unmodified or cyanotic at the top of the skin, with the growth of the tumor vascular skin gets sinebagrovy color.
When pressed hemangioma collapses and fades(Due to blood flow), with weeping, crying and coughing child increases and strains (erectile symptom that occurs as a result of blood flow). When skin hemangiomas usually clearly reveals a symptom temperature asymmetry - vascular tumor feels hot to surrounding healthy tissue.
Combined hemangioma area combination of surface and subcutaneous hemangiomas (simple and cavernous). They manifest themselves clinically, depending on the combination and the predominance of one or another part of the tumor vasculature.
Mixed tumor consist of hemangiomascells originating from blood vessels and other tissues (angiofibroma, gemlimfangioma, angionevroma et al.). Their appearance, color and texture are determined by members of the vascular tissue of the tumor.
Hemangiomas can be single and multiple. The majority of large hemangiomas were single and multiple tumors tend to be small. A group of patients with small and medium-sized hemangiomas superior group with large and extensive hemangiomas, treatment which is the greatest difficulty. The choice of method of treatment of extensive hemangioma is very problematic.
The favorite is the localization of hemangiomasthe head and neck. With this arrangement, the surgeon, prescribed treatment, seeking not only the therapeutic effect, but also the most advanced cosmetic and functional results. With the localization of hemangiomas on the trunk and extremities cosmetic outcome of the treatment is far less important. With the localization of hemangiomas in the trunk of most interest to practitioners is their location in the area of the breast and crotch. While localization of breast boys and girls the same approach to the treatment of hemangiomas they have significant differences. A feature of the flow of hemangiomas in the perineum and external genitalia is their tendency to frequent ulceration.
In children with hemangiomas may developthrombocytopenia - decrease in blood responsible for stopping bleeding cells, the congestion and the loss of platelets in the vasculature of the tumor (Kazabaha syndrome - Merritt). As noted above, some of the features of the course of hemangiomas is their tendency to frequent ulceration and self-healing, which makes doctors with extreme caution to treatment or, if possible, avoid it. When placing an ulcerated tumor vasculature in the region of the lips violated the act of sucking, in the nose, especially when the tumor is completely filled nasal passage - the act of breathing. Hemangioma ulceration in the vulva, especially the girls, causing severe pain and a burning sensation that affects heavily on the general condition.
