» Leucoderma Surgery
Leucoderma or Vitiligo [white patches] is a long
term skin condition that causes pale, white patches to develop on the skin.
Vitiligo or leucuderma is an auto-immune condition, where the bodys
own immune system may not recognize self and thus attack and destroy the
melanocytes resulting in lack of melanin, the skin pigment which gives skin
its colour and protects it from the sun.
Melanin is produced by melanocytes, which are special cells in the
skin.These white or pale patches can develop anywhere in the skin, but is
more common in the areas that are exposed to the sun, like face, neck and
hands. The pale patches can be small to begin with but may join to involve
large areas. These are more easily visible in darker skins. There are some
surgical techniques that can benefit vitiligo in stable disease.
This is a new technique which involves grafting of melanocyte cell
suspension Skin from an unaffected area is harvested and the layers
separated by incubating with an enzyme called trypsin. Autologous epidermal
cell suspensions allow large areas to be treated in one session using a
small donor graft. They result in excellent colour matching. Melanocyte
transplants have a very high success rate of 95 percent and this tecnique is
being performed at image medical centre.
Skin grafting This is a traditional technique in which,normal skin is
used as donor tissue and then grafts are surgically transplanted on areas of
vitiligo. The new skin grafts start producing pigment. The melanocytes in
the normal transplanted skin continue to produce melanin thus providing
pigment to darker the skin.Skin grafting has a high success rate 80
to 90 percent in most patients.
