Abstract
The elderly constitute a large and rapidly growing segment of the population; however, there is complete lack of information about the epidemiology of vitiligo in this age group. To study the clinical and epidemiological profile of vitiligo in the elderly, we retrospectively analyzed the data of patients with vitiligo having onset of disease after 50 years of age attending the pigmentary clinic of our center. Of the 182 patients, 87 (47.8%) were males and 95 (52.2%) were females. The mean age of onset of disease was 55 ± 2.3 years. Vitiligo vulgaris was the most common (83.5%) followed by focal (5.5%), segmental (4.4%), acrofacial (3.8%), mucosal (2.2%), and universal (0.5%). The most common site of onset was the head and neck (24.2%) followed by the upper limbs (23%), trunk (22%), lower limbs (17.6%), oral/genital mucosae (7.1%), and flexures (6%). Koebner's phenomenon was observed in 14.8% while leukotrichia was present in 47.3% of the patients. Halo nevi were observed in 3.8% of patients, and vitiligo was stable in 64.8%. Twenty‐nine (15.9%) patients had family history of vitiligo. Associated autoimmune autoimmune/endocrine disorders were present in 39 (21.4%) of the patients. Differences in disease characteristics compared with vitiligo in children and young adults are discussed.
