Cutaneous aspects of Down syndrome

Down syndrome is associated with an increased incidence of cutaneous manifestations such as atopic dermatitis, alopecia areata, elastosis perforans serpiginosa, syringomas, and skin infections. We describe 3 patients with Down syndrome: an 8-year-old boy with alopecia areata, a 17-year-old boy with crusted scabies, and a 39-year-old woman with a cutaneous collagen vascular disease-like disorder. We also review cutaneous signs of this syndrome.
