Nevus Depigmentosus

Picture of Nevus Depigmentosus

Nevus depigmentosus (achromicus). These are localized areas of hypopigmentation that are usually present at birth. The lesions may be irregular in size and shape and occasionally follow a linear or segmental pattern. Sometimes the lesions grow in proportion to the growth of the patient. If there are terminal hairs in the area of involvement they are not pigmented. Electron microscopic study of these areas suggests that melanosomes are not being transferred from melanocytes into surrounding keratinocytes. There are no associated abnormalities.
