Leucoderma is a cutaneous condition, an acquired condition with localized loss of pigmentation of the skin that may occur after any number of inflammatory skin conditions, burns, intralesional steroid injections, postdermabrasion, etc It is largely a cosmetic problem. . This occurs due to loss of melanin, a dark pigment which gives color to skin. It may begin with a small patch but slowly and steadily spreads throughout the body
Flat spots that range in color from white to pink to tan and brown appear over the upper arms, chest, back, neck and face. They vary greatly in size, from as small as four to five millimeters in diameter to large areas of confluence. Scaling may not be readily evident, but scales may easily be obtained by scraping the affected areas. A mild itch may be present, particularly if a person is sweating or feels hot. When the spots involve the neck or face, it can be very disconcerting.
It is important to remember that skin without pigment is at greater risk for sun damage. Be sure to apply a broad-spectrum (UVA and UVB), high-SPF sunscreen or sun block and use appropriate safeguards against sun exposure.
