What is nevus depigmentosus?

Nevus depigmentosus, or nevus Achromicus, is a skin problem in which the specific areas of the skin appear to be hypopigmented or depigmented. The lesions of this skin disorder occur as bright or white spots that are not raised, are congenital or congenital and are non -service or do not spread or spread with age. Unlike vitiligo, which is a multifactorial disease with epidermal melanocyte destruction, and albinism, which is the result of disorders of development or differentiation of melanocytes, Nevus Depigmentosus includes reduced melanocyte melanocyte production. It may also be wrong with a similarly looking skin disorder called Nevus anemicus, but unlike Nevus anemicus, it is not red after application of friction. Nevus depigmentosus cannot be treated, but can be hidden by appropriate use of cosmetics. They are usually limited to the trunk and upper arms and legs. The distribution formula may seem like a leaflet, linear or segmented. Approximately 19% of people have these lesions at birth.

In Nevus Depigmentosus, there is no inheritance formula, so it is not known whether this skin disorder is dominant or recessive. Most newborns with nevus depigmentosus have no manifestations until they become infants or toddlers. The main pathology of Nevus Depigmentosus is reduced melanin production, so localized albinism is not a correct description because albinism involves problems with the development or differentiation of melanocytes or cells producing melanin responsible for human pigmentation.

Diagnosis Nevus depigmentosus, dermatologists use several criteria, such as the presence of hypopigmented or white lesions from birth or at the beginning of life, lack of OFF change in distribution, lack of sensory interference in the affected area and lack of hyperpigmentation surrounding the affected area. Associated symptoms are very rare, although some patients have shown symptoms, JAKOs are seizures, mental retardation, sensitive leather and yellow hair. Patients have reduced melanin and are more susceptible to sleep burning, so it is best to use sunscreen or sunscreen products in affected areas. Probably the best way to deal with lesions Nevus depigmentosus, especially in self -confident individuals, is to use cosmetics to cover affected areas. Excision or removal of lesion by lasers can only be done if it is a small area of ​​the skin, while another treatment option, called melanocyte-keratinocytes (MKTP) transplantation, has a limited success.
