Abstract

Vitiligo is an acquired disorder of depigmentation affecting 0.1%-2% of the world’s population without discrimination of race, age and gender. The disease is characterized by white patches, often symmetrically distributed, which usually increase in size with time, corresponding to a considerable loss of functioning epidermal and sometimes hair follicle melanocyte. There are many treatment options available for the disease. Standardized guidelines for treating this disease in Asian skin are not readily available which leads to no set criteria for treating this cosmetically disfiguring problem. These guidelines have been prepared for dermatologists considering all the latest evidence based data available. Vitiligo is diagnosed clinically, although in some cases biopsy is required. Lesions on face and neck respond well to the treatment. However, segmental and acral types respond poorly to treatment. In the assessment of patient before starting therapy it is important to consider age, pre-existing diseases, in particular autoimmune disorders and previous medications. Topical corticosteroids and/or topical immunomodulators for localized vitiligo and phototherapy for generalized vitiligo are considered as first line therapies. As the treatment often extends over a long period of time, patients are frequently frustrated by the failure of previous treatments, so psychological stress is common and thus psychotherapy has also positive role. These comprehensive guidelines for the diagnosis and management of vitiligo in coloured skin aims to give high quality clinical advice, based on the best available evidence and expert consensus.
