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. Electron microscopic study of these areas suggests that melanosomes
are not being transferred from melanocytes into surrounding keratinocytes.
There are no associated abnormalities.
