The red spots on the back of the neck may be caused by nevus erythematosus, hemangioma, eczema and so on, which can be treated and removed by glucocorticoid drugs, laser and surgery.
1. Nevus erythematosus: nevus erythematosus is a kind of congenital capillary malformation, which often appears at the time of birth or soon after birth, the cause of which is still unclear, and manifests itself as light red, dark red or purplish-red patches of varying sizes, which is generally effective after regular laser treatment and is not easy to recur.
2. Hemangioma: hemangioma is congenital abnormal proliferation of blood vessels and endothelium, congenital benign tumors in skin and soft tissues, lesions manifested as congestive, abrasive or capillary dilatation plaques. Some benign hemangioma patients can subside on their own, if not subside for a long time, they can undergo surgical excision or laser treatment (such as pulsed dye laser, etc.).
3. Eczema: Eczema usually leads to skin rashes, itching and other symptoms, and may lead to red spots on the back of the neck after being stimulated by scratching. Mometasone furoate cream, hydrocortisone butyrate cream and other medications can be used for treatment under the guidance of a doctor, which can play a certain anti-inflammatory effect and improve the symptoms of eczema, thus facilitating the elimination of red spots.
Erythema on the back of the neck may have other causes (such as neurodermatitis, etc.), it is recommended to choose a regular hospital, actively cooperate with the doctor to identify the cause of the disease, and then targeted treatment.
