HEREDITARY ECTODERMAL DYSPLASIA OF THE ANHIDROTIC TYPE

This article is concerned with the presentation and discussion of a case of a relatively rare type of disease in an infant who first came under our observation at the age of 6 weeks. At that time we were impressed with the extreme degree of hyperthermia which the patient so readily exhibited. We were not satisfied that this high fever was due solely to infection. Within a relatively short time after his admission to the hospital, careful investigation and study enabled us to diagnose the condition as hereditary ectodermal dysplasia of the anhidrotic type. Indeed, had it not been for the hyperthermia it is doubtful that the diagnosis would have been made until much later, when it became apparent that no teeth were erupting. To date about 30 cases have been reported, only a fraction of these being of the anhidrotic type. REPORT OF A CASE H. C. J., 6
