Vitíligo: revisión bibliográfica.

Abstract

Vitiligo, from the Latin "vitium", which means spot or defect; is an acquired hypomelanosis, a depigmentation disorder characterized by the progressive destruction of melanocytes in the epidermis causing a loss of melanin. This pathology has been little studied due to its low incidence and low morbidity rates, however, being a visible disease with clinical presentation due to achromatic spots, it generates a high psychosocial impact on the patient's life with great influence on interpersonal relationships, for Hence, it should be considered of great clinical relevance. Its course is unpredictable and is usually progressive and although its etiopathogenesis is unknown, different theories have been presented, the autoimmune hypothesis being the most accepted at present. Generally, it is easy to diagnose since the total absence of pigmentation (acromia) makes it possible to exclude this pathology from others that present with hypochromia (low pigmentation), such as pityriasis versicolor, pityriasis alba, lichen sclerosus, among others.
