There are several disorders, other than Vitiligo, which lead to loss of pigment. Some of these disorders are listed below and can be treated with Melanocyte Keratinocyte Transplantation (MKTP).
Post Burn Leukoderma
A burn is a common accidental injury seen in medical practice. It results in scarring and fairly frequently, hypo or de-pigmentation. Normal pigmentation returns in many patients without any treatment, within about 6 months after complete healing.
Some patients however, experience permanent hypo/de-pigmented patches similar to that of Vitiligo. This is mainly due to mechanical destruction of melanocytes. Post-burn Leukoderma can be successfully treated by surgical transplantation methods. Any other medical treatment including photo-therapy is likely to be unsuccessful.
This is a hereditary disorder characterized by milky white patches of variable size and shape. These patches are present since birth and remain unchanged throughout life and are located on the front portion of the body (ventral part of the body).
This is a genetic disorder with complete absence of melanocytes. This disease does not respond to any kind of medical therapy.
Transplantation of melanocytes almost always gives excellent outcomes with very good re-pigmentation. Any surgical method will produce good results. Non-cultured epidermal cell transplantation may be the best option to treat large patches of piebaldism.
This is a localized hypo-pigmented non-progressive lesion, which remains unchanged throughout life. It appears at birth or within a few months of birth. The exact cause of Nevus is not known. Medical treatment, including phototherapy, is not effective. Transplantation methods have been tried to treat this disease with variable results.
Discoid lupus erythematosus
This disease can lead to scarred and de-pigmented patches on the face and upper chest. Usually these lesions fail to respond to medical treatments. There are only 2 reports in the literature, which show very good results with surgical treatment. However, more studies with long term follow up will be helpful to assess/prove the efficacy of surgical therapies.
Leukoderma caused by laser
Lasers have been increasingly used in dermatology to treat vascular disorders, hair removal, hyper-pigmented disorders, tattoo removal etc. These treatments sometimes lead to white spots. Melanocyte Keratinocyte Transplantation (MKTP) may be used to treat these white patches with good results.
Chemical Leukoderma (contact Leukoderma)
Certain chemicals like quinon and hydroquinone cause pigment cell destruction leading to white spots. These chemicals are present in industry and cosmetics. Occasionally phenol or tricholracetic peeling may also lead to white patches. MKTP can be considered to treat such lesions.
Halo nevus consists of a pigmented mole surrounded by sharply outlined area of de-pigmentation. Although it is often associated with Vitiligo, in most cases it is a separate entity. Sometimes the pigmented mole disappears spontaneously and the de-pigmeted area pigments spontaneously. These nevi have been successfully treated by transplantation methods when they become stable.
