The most common places to find this disease would be on the hands, feet, around the mouth and eyes, and even around the genitalia. With some skin diseases, melanocytes are destroyed, and the production of melanin, a dark brown to black pigment that is found in the skin and is the reasoning for skin color, is simply just slowed down. This results in hypopigmentation, which is the loss of skin color, but not a total loss. Other skin diseases, such as vitiligo, have a complete absence of melanin. The depigmented skin color of someone with this disease is similar to that of one who suffers from albinism. The destruction of melanocytes can have three major causes in people with vitiligo. The first being that a patient with vitiligo has inherited three of the “vitiligo” genes, which has caused their melanocytes to destruct. The second being that the melanocytes themselves are different in a patient with vitiligo in relation to those without vitiligo. Melanocytes of a vitiligo patient compared to a person without vitiligo require a meticulous cultural condition and are more unstable around certain chemicals. The cells can even die when exposed to such factors. Vitiligo genes are prevented from acting in a normal fashion when they are
