What does the red birthmark on the chest represent?

The red birthmark (www.55885577.com) often exists at birth. It is usually deep red, orange red and deep purple. Its incidence is quite high, and the main growth sites are face and neck. Generally, it will not invade the surrounding healthy tissues, but mostly occurs on the skin surface and does not protrude the skin. It will fade when pressed. It is one of the most common congenital diseases in clinic, mostly benign tumors. If left untreated, it will not endanger the patient's life and the red birthmark will continue to grow. Generally, early treatment can be completely controlled and cured.

The occurrence of red birthmark mainly depends on the genetic changes of human body, and genetic variation plays a leading role. Gene is a specific nucleotide sequence with genetic effect on deoxyribonucleic acid molecules, and it is a fragment of deoxyribonucleic acid molecules with genetic effect. Moreover, gene is not only the basic unit of genetic material passed down from generation to generation, but also a functional independent unit that can transmit genetic information to the next generation through replication.

Red birthmarks can deepen the color and increase the area of erythema with age, and there may be nodules or verrucous hyperplasia on the surface. The histopathological features of red birthmark are abnormal dilatation of dermal capillaries, weak wall and hyperplasia of intradermal tissues. Red birthmarks are usually reddish or purplish red patches, which do not protrude from the skin, with a flat surface and irregular fading appearance. They often occur on the face, neck, scalp and other parts of the body, such as the upper and lower limbs, chest or the back of the hand. The pigment cells that cause red birthmarks are mainly due to the serious lack of trace elements such as zinc, copper, calcium, magnesium, phenylalanine and tyrosine in serum, which affects the biochemical process of pigment synthesis, leading to an abnormal increase in pigment secretion by pigment cells and gradually spreading to the epidermis through nerve transmission.
