Babies born with birthmarks may be due to bright red nevus, hemangioma, nevus Ito, Mongolian spots and other factors.
1. Nevus erythematosus: the etiology of nevus erythematosus is not clear, it may be related to nerves, cytokines, genes, blood vessels, and other factors, and for babies born with birthmarks, this may be due to family aggregation of heredity.
2. Hemangioma: the pathogenesis of hemangioma is still unclear. It may be due to the balance imbalance between angiogenic factor and angiogenic inhibitory factor, which leads to gene mutation, causing local skin and endothelial cells to have abnormal transformation, so that babies appear to have birthmarks after birth.
3. Nevus of Ito: When the baby will have nevus of Ito, it will also cause birthmarks, which is mainly related to genetic factors.
4. Mongolian spots: Mongolian spots are related to genetic factors, mainly because melanocytes stay in the deep dermis when they move from the neural crest to the epidermis in the embryonic period, so babies will have birthmarks since birth.
Babies born with birthmarks, there may also be other reasons, it is recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
