Hemangiomas, more commonly known as red moles, are benign growths that originate from blood vessels.
What is a red mole? Why are these moles red? The fact is that in fact they represent a vascular tissue that is filled with blood. If ordinary moles are skin formations, then red moles are several small overgrown blood vessels. With a pronounced process, such clusters merge into a single spot of burgundy or blue color. localization and distribution.
In most cases, such vascular tumors are diagnosed immediately after the birth of plaquenil pills, while in 70% of cases the patients are girls, who thus constitute a high-risk group.
This pathology accounts for 48% of the total number of all tumors of the skin and soft tissues in childhood. On the body of a child, red moles can be localized in absolutely any part, while about 80% of tumors are located in the upper body. Quite rarely, such formations are present on the internal organs - bones, lungs, brain, liver. Approximately 95% of all diagnosed tumors are simple formations.
About 2% are combined and mixed variants of the pathology.
How does this happen? In the process of laying down systems and organs, vascular tissue permeates all parts of the body along a certain chain consisting of pericytic cells. Such cells act as a kind of information conductor and react to the slightest lack of oxygen: if the tissues of the fetus suffer from hypoxia, the synthesis of special proteins that attract pericyte cells immediately starts.
What is the reason for the appearance of such formations is still not known exactly. It is also difficult to explain why there are a large number of moles of a similar nature in the face area. It is likely that this is due to the abundant vascular network that supplies the tissues of the face.
Approximately 3% are cavernous.
These cells begin to forge new pathways for blood supply to tissues, fighting hypoxia. In some cases, even after the end of the lack of oxygen, protein synthesis continues, respectively, the vascular tissue continues to develop and begins to form tumor-like formations.
There are suggestions regarding the negative effects of radiation and ultraviolet exposure, chemicals and viruses, which provoke the growth of tumors in adults.
The second name of vascular moles is vascular hyperplasia. Thus, we can say that the tumor is formed as a result of a violation of the process of growth of vascular tissues, which provokes an increase in its number. It is rather difficult to answer with absolute certainty how and how this process occurs, since for this it is necessary to carefully monitor all the features of the intrauterine development of body tissues. The given data are based on the results of the autopsy of stillborn and aborted fetuses.
