The incidence of vitiligo at King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia was 2.5% for the period from 1985-1990. The majority (96.1%) were Saudis. Approximately 64% were below the age of 30 years and the average was 25.6+/- SD 13.7 years. Fifty-six percent of the patients were males and 43% were females. More than half of the patients had the lesions for a period between one and nine years and 17.17% had them for more than 15 years. Only 12% had a positive family history of vitiligo. The majority (54%) of the lesions were in exposed areas. The associated diseases with vitiligo are also reported.
