Hypohidrotic ectodermal dysplasia - a case report / Hipohidrotska ektodermalna displazija – prikaz slučaja

Ectodermal dysplasias are a large group of disorders characterized by developmental dystrophies of one or more ectodermal structures. Hypohidrotic ectodermal dysplasia is a rare genodermatosis associated with abnormal development of sweat glands, teeth, and hair. Its incidence is 1:100.000 newborns. The full expression of X-recessive forms are only seen in males, while female heterozygotes are moderately or very slightly affected. The disease is characterized by sparse hair, oligodontia, and reduced or absent sweeting, light hair, distinctive facial features, palmoplantar keratoderma.

We report an 11-year-old boy with hypohidrotic ectodermal dysplasia. Despite extensive skin, teeth and hair manifestations, his physical and psychomotor growth and development were normal.
