Unexplained Fever in Infancy: Report of a Rare Case of Hypohidrotic Ectodermal Dysplasia in an Infant.

Hypohidrotic ectodermal dysplasia (HED) is a genetic condition that affects structures derived from the ectoderm during embryonic development. These structures include the outermost layer of the primary germ layers, which give rise to various body parts such as the ears, eyes, lips, and mucous membranes of the nose and mouth. Due to the impact on these structures, hypohidrotic ectodermal dysplasia can manifest differently in various age groups.
