Dysphagia in hypohidrotic ectodermal dysplasia. A case report.

The congenital ectodermal dysplasias are a rare group of hereditary disorders manifesting with variable defects in structures of ectodermal origin. This report describes a patient with the hypohidrotic form of ectodermal dysplasia who presented with dysphagia and pneumonia. He was shown to have laryngeal incompetence and it is postulated that this may be a mechanism for the recurrent chest infections reported in patients with this condition.
