Introduction
Facial birthmarks in newborns may be caused by genetic factors, environmental factors, café-au-lait spots, strawberry hemangiomas, lymphangiomas, or other causes, and require appropriate management depending on the specific condition. After a facial birthmark appears in a newborn, close observation of any changes in the birthmark is necessary, and medical attention should be sought promptly if abnormal enlargement, color changes, or other issues occur.
Birthmarks on a newborn's face may be caused by genetic factors, environmental factors, café-au-lait spots, strawberry hemangiomas, lymphangiomas, and other causes, and require appropriate management depending on the specific situation. Detailed analysis is as follows:
1. Genetic factors: If parents or close relatives have birthmarks, the likelihood of a newborn developing birthmarks increases. It is recommended to consult a doctor and consider treatments such as laser therapy, cryotherapy, or skin grafting.
2. Environmental factors: Exposure of pregnant women to chemicals, radiation, or similar substances during pregnancy may affect fetal skin development and lead to the formation of birthmarks. Pregnant women should avoid contact with these substances as much as possible and minimize the use of electronic devices that emit significant radiation.
3. Café-au-lait spots: These are caused by abnormal increases or uneven distribution of skin pigment cells. Generally, café-au-lait spots do not require treatment, but if they affect appearance, options such as laser therapy or chemical peeling may be considered.
4. Strawberry hemangioma: This type of birthmark consists of abnormally proliferating blood vessels that form red or purple patches under the skin. Small hemangiomas may not require treatment, while larger ones or those affecting appearance or function can be treated with cryotherapy, oral propranolol, or topical timolol gel.
5. Lymphangioma: Lymphangioma is a rare structural birthmark presenting as a lump beneath the skin or mucous membranes, typically composed of abnormally growing lymphatic vessels. Surgical removal may be necessary to prevent infection or improve appearance. After surgery, antibiotics such as amoxicillin capsules, cefradine capsules, or azithromycin capsules may be prescribed under medical supervision to prevent infection.
After a newborn develops a facial birthmark, it is important to closely monitor any changes. If the birthmark shows abnormal growth, color changes, or other concerns, prompt medical evaluation is advised.
