Vitiligo is an acquired chronic skin disorder of pigmentation, which is characterized by white patches due to loss of pigment producing cells in the skin. These white or hypo-pigmented white patches are the hallmark, and the main Vitiligo symptom. These white patches are frequently symmetrical and their size usually keeps increasing with the passage of time. This is associated with a significant loss from the epidermis and also from the hair, of functioning melanocytes.
Segmental Vitiligo is a type of Vitiligo in which Vitiligo is limited to one segment on one side of the body. Vitiligo symptoms may remain confined to only one segment or may involve some segments on the same or the opposite side as well.
Vitiligo symptoms have been seen to follow the dermatomal pattern as well.
In symmetrical Vitiligo, the Vitiligo symptoms commonly affect the fingers , the wrists, the armpits, and the groins. Vitiligo symptoms are also commonly complained regarding natural orifices of the body like the mouth, nose, eyes and the genitalia
A “Trichrome” appearance is frequently presented as a Vitiligo symptom, where the depigmented patches are seen in the form of three different zones of color. The center is white or near white, surrounded by a zone of less severe depigmentation and a color which is midway between white and the native skin that surrounds the lesion.
The skin surface is usually not affected and redness is complained only as a Vitiligo symptom when the depigmented skin is exposed to scorching sun / UV light.
Inflammation in the advancing edge of a white patch may also present as Vitiligo symptoms.
Vitiligo symptoms may affect the hair roots in severe cases when hair in the affected areas may also lose their color, and loss of pigment from the mucosal surfaces is not an uncommon symptom of Vitiligo either.
Presentation of pityriasis versicolor, piebaldism and guttate hypomelanosis can resemble the symptoms of Vitiligo and may need to be differentiated.
