Leucoderma or white patches appear over scalp, forehead, eyes, behind ears, over lips, neck and have the tendency to spread in down-ward direction, i.e. , over back, abdomen, thighs, knees, lower legs, arms, hands and feet. Leucoderma of old people becomes difficult to cure (due to old age weakness), or when it appears over lips, palms and soles (due to frequent rubbing action between wet lips, between hands while washing them with soap and between sole and shoe. Moreover, the skin of the sole is very thick, hard, and does not contain any blood vessel. It is commonly seen among weak children and is more common in the black races, in meat-eaters or in those who avoid eating vegetables.
Causes : All injuries, wounds, ulcers, boils, burnt skin with fire or hot coal, hot liquids, etc., destroy the skin and its chromatophores (special cells in the skin on which colouring matter melanin is contained). It is also found in hair and eyes. Melanin is a dark brown or black pigment which is found in the chromatophores, hair and the choroid layer of the eye-ball between the retina and the sclera which contains blood vessels and black pigment that absorbs excess light and so prevents blurring of vision.
Melanocyte (melanophore) is a cell within the epidermis of the skin that produces the dark brown or dark pigment melanin. Thus, in injuries, wounds, ulcer or in burnt skin these melanocytes are destroyed and as such they do not manufacture the colouring matter melanin and so the affected spots on the skin turn into white scars and at later stage these scars change into leucoderma.
