  2. What is Vitiligo? It is a pigmentation disorder in which melanocytes in the skin are destroyed.

  3. Causes The cause is ultimately unknown, but doctors and researchers have numerous theories. • People inherit a group of 3 genes which make them susceptible to depigmentation • Autoimmune disease ( a disease in which the body’s immune system reacts against the body’s own tissues and organs Myths • Sunburn • Sudden Emotional Distress

  4. Signs and Symptoms • Sudden white patches, mostly on the sun exposed sections of the body. (eyes, lips, legs, arms, feet, hands and face) • Other common areas are arm pits, groin, nostrils, genitals, rectum and naval. Patterns • Focal- depigmentation limited • Segmental- depigmentation occurs on one side of the body • Generalized- depigmentation occurs all over the body

  5. Continued…. • People may notice gray body hair forming (growing) • Dark skinned people often begin with discoloration of the mouth

  6. Treatments, Cures, Prevention • Topical Steroids- topical steroid cream that must be applied to epidermis during initial stages of Vitiligo; must be used for at 3 months to see repigmentation • Psoralen Photo chemotherapy (PUVA)- seen to be the most effective method to regain pigmentation. However, it is very time consuming. Also known as Ultraviolet therapy. Psoralen is a drug that chemically reacts with ultraviolet light. This method of repigmentation can be used orally, and topically. Side effects may but are rarely severe. Doctor supervision s required.
