    The ectodermal dysplasias (EDs) are a heterogeneous group of inherited, developmental disorders characterized by alterations in two or more ectodermal structures including the hair, teeth, nails and sweat glands. Currently, more than 200 types of ectodermal dysplasias have been described. Anhidrotic or hypohidrotic ectodermal dysplasia (AED/HED), the most common ED, is characterized by three cardinal features: hypotrichosis, hypohidrosis and hypodontia. We review the genetic and pathogenetic mechanisms of AED/HED and report on the management of clinical manifestations driven by embryology, anatomy and physiology.
