Abstract
Background: Vitiligo is an acquired, multifactorial disease of the skin and mucous membrane characterized by depigmented macules. It can be mainly differentiated into segmental and non-segmental vitiligo. Diagnosis is usually by clinical examination and wood’s light. There are several treatment modalities among which are systemic and local medications, phototherapy, lasers, surgical interventions and camouflage. Dermoscopy is an important diagnostic and follow up tool in dermatology clinics. In this study we assessed the value of dermoscopy in evaluation of four different treatment modalities in vitiligo patients.
Subjects and Methods: This study was carried out on 60 patients who were divided into four groups of 15 patients each according to treatment modality used:
• Dermabrasion with Erbium YAG laser followed by application of 5Fluro-Uracil cream.
• Topical Immunomodulator.
• Excimer light.
• Narrow band ultraviolet beam (NBUVB).
Four visits were documented for each patient (before treatment, after one week, after one month and after 3 months). Photographic and dermoscopic documentation were done each visit.
In this study we decided to emphasize on five main findings (erythema, hair color, repigmentation, peri-lesional hyperpigmentation and telangiectasia).
