Nevus of animal skin is a kind of congenital melanocytic nevus. Some babies have skin moles at birth, which worries their families. The following is what I brought about the causes of neonatal nevus. Welcome to read!
1. Gene
Animal skin nevus is a kind of birthmark, and the major factor affecting its formation is genetic genes. Gene is a basic unit for the transmission of genetic material between upper and lower generations. It transmits genetic information to the next generation through replication. For example, coffee spot is a birthmark generated by genetic inheritance. Genetic dominance and recessive inheritance will cause some people to have birthmarks due to genetic inheritance, while others will not. Those patients who do not have a birthmark due to recessive inheritance may still have a birthmark in the next generation because they simply do not show it because they carry a genetic gene.
2. Environment
As another factor related to the formation of nevus, environmental pollution is actually rooted in genes, but it is not gene replication, but variation.
Environmental pollution leads to the deterioration of people's living space. A large number of pesticides and pesticides on vegetables, as well as growth hormone and contraceptives in meat such as chicken and fish, will cause genetic variation in embryos that are still pregnant, resulting in the emergence of various birthmarks.
Animal skin nevus is a kind of congenital melanocytic nevus. It is the abnormal proliferation of skin tissue during development, and the abnormal shape and color appear on the skin surface. Melanocytic nevi vary in size, a few millimeters small. If the diameter is more than 20cm, they are called giant melanocytic nevi. Some patients even most of their trunk or whole limbs are covered with large melanocytic nevi, and there are often many thick black hairs on the surface. At this time, they are called dermoid nevi. The incidence of malignant melanoma in giant melanocytic nevus is significantly higher than that in other types of melanocytic nevus, up to more than 10%, which mainly occurs in the pre puberty age of patients.
1. Go to the hospital for resection
Animal skin nevus can be effectively treated in plastic surgery hospital. It needs surgical resection and skin grafting, but the operation cost is large. There are many surgical methods to remove animal skin nevus, which can be directly removed, and the skin graft donor area can be selected in the thigh.
Advantages: its advantages are to solve problems at once;
Disadvantages: the skin graft area will have obvious pigmentation and scar in the thigh donor area in the long term.
2. Expander method
To get rid of animal skin nevus, you can also choose the method of expander, that is, first embed the expander in the normal skin around you and inject water into the expander intermittently. It takes 2-3 months to expand the normal skin, and then remove part of the nevus. Such a course of treatment takes about three months.
Advantages: it is close to normal skin, but there are additional scars;
Disadvantages: it takes a long time and costs a lot.
1. Giant animal skin nevus is a congenital nevus. It is a congenital disease, which is difficult to treat. Parents should pay attention to it.
2. Don't rub, corrode or stimulate animal skin nevus at ordinary times, so as to prevent the rapid differentiation of cancer cells and malignant transformation.
3. Special attention should be paid to animal skin nevus with sudden increase, deepening color, rough surface and keratosis, and go to the hospital for treatment as soon as possible.
4. Experts say that for the treatment of nevus, patients must choose a regular and professional nevus hospital. Do not use drugs or folk prescriptions without authorization to avoid aggravating the condition due to improper treatment. Now laser treatment is an ideal choice for patients.
