Infantile bright red spot, also known as infantile bright red nevus, is a skin disease caused by congenital vascular malformation, also known as dilated capillary nevus or wine-like nevus. At present, the specific cause of the disease is not clear, and it may be related to factors such as nerves, blood vessels, cytokines, genes and so on. It usually occurs on the face, neck and other parts of the body. It is a red or purple patch with irregular shape, which often appears at birth or soon after birth. Most of them appear unilaterally, occasionally bilateral erythema, sometimes also involving the mucous membranes. In some cases, the redness fades or disappears with age, but in most cases, it persists for life. Currently, the most common treatments include laser treatment, medication and surgery. The size of the lesion, its condition, and the presence of complications should be evaluated under the guidance of a doctor before choosing the treatment. Parents are advised to consult a dermatologist promptly if they find infants with light or dark red patches on the head and neck or other parts of the body, especially when the lesions appear on the head and face areas, affecting the appearance of the face.
