Nevus vascularis

nevus vascularis –>
capillary haemangioma
(Science: dermatology) red or purple-coloured vascular skin markings that develop shortly after birth. Most are usually painless and benign and sharply demarcated from surrounding skin, usually located on the head and neck, and grow rapidly.
It is caused by proliferation of immature capillary vessels in active stroma, and is usually present at birth or occurs within the first two or three months of life.
Some lesions (cavernous haemangioma) will disappear or become harder to see as the child approaches school age.
localised steroid injections have been used successfully to reduce the size of a birthmark but generally they undergo spontaneous regression and involution without scarring and normally require no treatment.
