Leucoderma, also known as vitiligo, is a distressing skin condition. The word literally means white skin. There is a gradual loss of pigment melanin from the skin layer which results in white patches. These patches look ugly, especially in persons with a dark complexion. The attraction in colour is the reason for huge sales of fairness creams. But the whiteness offered by skin disease - leucoderma - is often depressing for all the sufferers. As such it is hardly a disease of medical significance but more of a social stigma attached to it because of cosmetic reasons. The condition does not cause any organic harm. It , however, brings about great psychological tension to the patient who is more embarassed than the victim of any pain or discomfort. Patches can be caused because of a number of reasons, the most common among them being worms and calcium deficiency. These patches gradually increase in size & cause lot of psychological stress in the patient. It is an auto-immune condition and may have a genetic predisposition.

This disease is caused neither by any germs, nor is it due to bad blood. It is considered to be neither infectious nor contagious. It is present in the basal layer of the epidermis and the first layer of the dermis, i.e. melanin is present in two layers. It is, however, more common in women than men. The most affected areas are the hands, the neck, the back and the wrist in that order. Leucoderma does not cause any health problems - it is not contagious or dangerous at all. It is only a cosmetic problem.

Moreover, it is just as important to remember that every white patch is not leucoderma. Patches can be caused because of a number of reasons, the most common among them being worms and calcium deficiency. In majority of the cases, medical therapy only achieves stabilization of the vitiligo patch but fails to cause repigmentation. If a patient of leucoderma is found to be suffering from digestive disorders, they should be treated first. When leucoderma occurs without any preceding disease it is called vitiligo . Sometimes it follows burns and injuries.
