The vitiligo is a benign, no contagious disease and unknown cause which passes on with the death of melanocytes or responsible cells of the pigmentation of the skin. The death of melanocytes entails the absence of melanin (responsible substance of the pigmentation of the skin). It can also affect to the eyes and the mucosa membranes.<\/p>\n

The vitiligo is a degenerative disease which passes on with irregular white spots starting between ten and thirty years old.<\/p>\n

The main feature of the white spots is that they are circular, of changeable size, delimited edges and with possibilities of extension.<\/p>\n

The causes of the vitiligo are not very well delimited although it seems to be that it could be because of:<\/p>\n

a)\u00a0\u00a0\u00a0\u00a0 Autoimmune processes: some activated lymphocytes destroy the melanocyte. We have to consider that the vitiligo is associated with autoimmune diseases like Addson’s disease, hyperthyroidism or pernicious anemia.<\/p>\n

b)\u00a0\u00a0\u00a0 Neurogenous processes: the interaction between melanocytes and nervous cells would release a toxic neurochemistry substance which would destroy melanocytes.<\/p>\n

c)\u00a0\u00a0\u00a0\u00a0 Self-destructive processes: the destruction of melanocytes would be a consequence of toxic substances created during the biosynthesis process of melanin.<\/p>\n

The lesions are usually whitish and well-defined borders according to two kinds of distribution:<\/p>\n

  1. No segmental (type A). The spots usually appear with some symmetry through the body and they are classified in several subtypes:<\/li>\n<\/ol>\n
