There was a red birthmark on my back when I was born ... What does that mean?

Red birthmark is a port wine nevus commonly known as capillary hemangioma in medicine. Pigment cells that cause red birthmarks are plaques formed by serious lack of trace elements such as zinc, copper, calcium, magnesium, phenylalanine and tyrosine in serum, which affects the biochemical process of pigment synthesis, leads to abnormal increase of pigment secretion by pigment cells and gradual spread of epidermis through nerve transmission. But the red birthmark with neat edges spreads slowly.

The area of the red birthmark will gradually expand with the patient's age, the color will become deeper and deeper, and the patient's lesions will gradually deepen. The area of red birthmark will become larger and larger, which will not only seriously affect the beauty of patients, but also cause bad psychology and serious psychological burden to patients.

Because the red birthmark is caused by vascular malformation, and the disease occurs in epidermis and dermis, the affected part of the patient may often be rubbed or scratched, thus causing ulceration and bleeding, especially in summer, because of the hot weather, it is easy to sweat, and the patient will itch when sitting on the skin. Because of frequent scratching, it leads to a lot of bleeding for a long time. The danger of red birthmark after ulceration and bleeding is easy to be infected.
