Overview
Vitiligo is a chronic skin condition that causes loss of pigment, resulting in irregular pale patches of skin that may be distributed according to different patterns.
Physical Examination
Skin
Irregular pale nonscaling macules of skin with different sizes, are present. These may be distributed under 5 general patterns:[1]
- Bilaterally distributed, in a symmetrical manner, located on the trunk, face and extremities.
- Segmentally distributed, occupying one whole side of the body or simply one single site.
- Acrofacially distributed, located in areas such as: perioral area, lips, hands and feet.
- Universally distributed when occupying more than half of the body surface area.
- Mixed distribution, combining different patterns described above.
In some occasions the border limits of these lesions may be erythematous. Also, hair and mucous membranes are often affected, appearing hypopigmented.
After adequate evaluation of the skin of vitiligo patients, the hypopigmented lesions should also be evaluated in a dark room, under the Wood's light. This is a source of UVA light that allows the evaluation of the skin areas with depigmentation, enhancing the details and tones of these areas. Areas such as axillae and genitalia should be evaluated carefully, since these are frequently involved regions that may be missed without the test.[2]
