How is brown birthmark formed

summary

Birthmark is a common phenomenon in our daily life. My eldest cousin's child has a brown birthmark on his face. He went to the hospital for examination. The doctor also told us about the cause of the formation of the brown birthmark.

How is brown birthmark formed

The first reason is that the cavernous Brown birthmark is formed by the growth of endothelial cells. It is worth noting that the actual volume of the cavernous Brown birthmark is difficult to see from the surface.

The second reason: capillary Brown birthmark is formed by superficial capillary dilation, circuitous and bending. It is mostly seen in the skin of the whole body. The color is dark red, and the shape is flat or slightly raised. Some brown birthmarks are also found in mucous membrane, brain, bone and other places.

The third reason is that the tortuous Brown birthmark is composed of extremely dilated blood vessels with different diameters. The arteries and veins in the tumor communicate with each other, and the distal veins become dilated and thickened, while the proximal arteries become dilated and thinned.
