What causes hemangioma?

summary

In the process of human embryonic development, especially in the early stage of vascular tissue differentiation, due to the small-scale dislocation of its control gene segment, it leads to abnormal tissue differentiation in specific parts and develops into hemangioma. In the early stage of embryo (8-12 months), the embryonic tissue suffered mechanical damage and local tissue bleeding, resulting in the distribution of some hematopoietic stem cells to other embryonic cells, some of which differentiated into angioid tissue and eventually formed hemangioma. What causes hemangioma? Next, I'd like to share my views with you.

What causes hemangioma?

First, hemangioma is composed of a large number of proliferative blood vessels. In the early embryonic stage, the primitive vascular network is a tube composed of endothelial cells. They form a dense network in the interstitium. Later, with the development of various organs, the primitive vascular network gradually differentiates into many vascular plexus and lymphatic plexus connected with organs.

Second, the embryonic development of blood vessels can be divided into three stages: plexiform stage, reticular stage and tubular stem stage. If there are obstacles or abnormalities in the normal development process of a certain stage, the malformation of normal development morphology of that stage can appear. In plexiform stage, if some capillaries stop developing, they will produce capillary hemangioma; In the reticular phase, cavernous hemangioma can be seen if the enlarged vessels are clustered and tend to fuse together.

Third: capillary hemangioma has well-developed single-layer endothelial cells and a small amount of connective tissue as the matrix. There are only a small number of blood cells in the lumen. It is a localized lobulated mass with clear boundary, slightly protruding from the skin surface, bright red in color and different in size. Due to the narrow lumen, it seldom turns white when compressed.

matters needing attention

1. Pregnant women should pay attention to increase or decrease clothes, pay attention to climate change, prevent the occurrence of diseases, and do not use drugs as much as possible. 2, your mothers avoid using perfume and cosmetics. Some cosmetics contain hormone drugs. It is easy to cause disorder of human hormone level and become the inducement of hemangioma. 3. Life should be light diet, eat more fresh fruits and vegetables, to ensure the unobstructed stool, balanced nutrition, not overeating.
