Abstract
Seventy‐one children with Down syndrome who were admitted consecutively to Hacettepe University Children's Hospital Genetics Department were examined for skin disorders. None of the patients suffered directly from skin disorders. All were living with their families and had approximately similar living conditions. There were 29 children with palmoplantar hyperkeratosis (40.8%), seven with xerosis (9.8%), 22 with seborrheic dermatitis (30.9%), 14 with fissured tongue (20%), eight with geographic tongue (11.2%), and nine with cutis marmorata (12.6%). Nine had normal skin findings. Since palmoplantar hyperkeratosis may be a result of vitamin A deficiency, the serum vitamin A levels of these patients were evaluated. There was no statistical difference between vitamin A levels of the children with Down syndrome and the control group.
