Certain skin condition can be treated only by complete surgical excision or removal of a piece of thick skin (including epidermis, dermis and subcutaneous fat). Only a dermatologist or plastic surgeon can decide when this technique is necessary.
Punch Biopsy can be used to treat stable patches of Vitiligo. The depigmented skin is removed using different punches and the normal skin is used to fill the defects.
Tatoos andtheir removal
A person who has a tattoo may later want it removed for personal or aesthetic reasons. But removal may also be medically desirable, for example, if the tattoo causes an allergic reaction or becomes the centre of a localised skin condition.
The only way to eliminate all particles of pigment entirely may be to remove the whole tattoo and cover the area with skin grafted from another part of the body. With large areas, dermabrasion or laser may succeed.
Tattooing itself is a technique that has some cosmetic application, in that it can be used to camouflage pigmented areas or birthmarks.
