title: Keratosis punctata of the palmar creases.
abstract: We compared the prevalence of keratosis punctata of the palmar creases among populations living in Belgium, Togo, Peru and the United Arab Emirates. It appears that black Africans and Hindous (prevalence 1 to 2%) are more often affected than Latin Americans (prevalence less than 0.1%). The disease was not seen among Europeans and Arabs. Histologically, the lesions consist of a marked hyperkeratosis located at the site of acrosyringia. The disease should therefore be considered as a sweat gland disorder.
