Vitiligo: clinical findings in 1436 patients.

We retrospectively analyzed the clinical and epidemiological profiles of patients with vitiligo attending the pigmentary dermatoses clinic. One thousand four hundred and thirty-six patients were seen between 1989 and 1993. Males constituted 54.5% of the group and females 45.5%. Mean age of the patients was 25 years, and average disease duration at the time of hospital visit was 3.7 years. Vitiligo vulgaris was the commonest form of the disease in 1002 (69.8%) patients followed by focal vitiligo in 214 (14.9%) and segmental vitiligo in 72 (5.0%). The sites of onset were the face, trunk, and legs in descending order of frequency. Less than 20% body area involvement was seen in 1356 (94.4%) of the patients. Leukotrichia was present in 165 (11.5%), and Koebner's phenomenon was observed in 72 (5.0%). Twenty nine (2.0%) patients had associated halo nevi. Of the various diseases associated with vitiligo, atopic/nummular eczema was seen in 20 (1.4%) patients, bronchial asthma in 10 (0.7%), diabetes mellitus in 8 (0.6%), thyroid disease in 7 (0.5%), and alopecia in 6 (0.4%).
