These are either pigmented lesions or some kind of vascular malformation. They usually require combinations of laser technologies. Before lasers, they were being treated by surgery, which inevitably will leave scar. Many of them could not be treated at all or treated unsatisfactorily.A birthmark is a blemish on the skin formed before birth. Though birthmark is formed before birth, they do not necessarily appear on birth. Many Birth Marks appear after birth, usually in first few months after birth, some of them although appear in second decade (10 to 20 years).
Birth Marks are of different color. When on hidden portion their existence doesn’t matter. Birth Marks on the visible areas can be problematic & pose social & aesthetic problem.
They are part of the group of skin lesions known as “naevi” or heamangioma. They are not hereditary. They are soft raised swellings on the skin or flat lesions. Naevi are often black due to increased melanin content in the cells viz. Melanocytic naevous, Giant hairy naevous, Bakers naevous, Linear neavous, Verucus naevous etc. When the excess melanin is located in dermis they look greenish Naevous of otta. Naevous may be brownish in color due to increased blood vessel cells – strawberry naevi or infantile haemangiomas.
The haemangiomas are vascular malformations situated in skin Portwine stain (capillary haemangioma). When they extend in deeper tissues subcutaneous fat & muscles ½ cavernous haemangioma.
Birth Marks needs combinations of lasers AFT 540, Diode, Q-switch Nd-Yag 1064 & 532, Er-Yag 2940 & Pixel Er-Yag 2940 lasers. Complete remission of naevi is possible many times. In case of Naevous of otta 80 to 90% remission is considered as good result. Haemangiomas 100% remission is extremely rare. One should feel happy with 70 to 90% remission.
