Author: Dr Adithi Jain
Background: Vitiligo is a common pigmentary disorder of the skin that has a worldwide incidence of 1%. As most of the studies and published articles available are based on a western population, more studies are required in Indian patients.
Material & Methods: This is a observational study done on out patients with vitiligo reporting to OPD in Department of Dermatology, venerology & leprosy, at National Institute of Medical Sciences & research and Hospital, Jaipur from January 2017 to June 2018. Based on the history and examination, a clinical diagnosis of the type of vitiligo was made. These details were entered in the specified proforma. Each enrolled patient was subsequently subjected to dermoscopy.
Results: Our study showed that the minimum age was 16 years and maximum age was 70 yrs. Maximum number of cases were in the age group >45 years. In all age groups, males (61.6%) outnumbered females (38.4%). Male to female ratio was 1.6:1. Most common dermoscopy finding among new lesions of vitiligo was salt & pepper pattern, which was found in 46 (76.67%) patients. In old lesions was that of telangeictasia, which was found in 46 (76.67%) patients.
Conclusion: We concluded that dermoscopy can be used as an effecient, safe and non-invasive tool to monitor the disease activity, response to the treatment and hence prognosis of the disease. Patterns such as trichrome, polkadot, starburst and comet tail, when present are suggestive of a change in treatment modality.
