Hypohidrotic (Anhidrotic) Ectodermal dysplasia — A rare cause of childhood Atrophic Rhinitis”

Hypohydrotic (Anhidrotic) Ectodermal dysplasia is a rare hereditary genodermatosis characterized by a triad of defects including hypohidrosis hypotrichosis and anomalous dentition. Mainly ectodermal structures are involved such as epidermis and its annexes (hair & nails), although non-ecotodermal tissue may also became involved(1). ENT involvement in such cases is a consequence of the defect involving the eccrine and sebaceous glands. A case of a 3 years old female child suffering from hypohidrotic ectodermal dysplasia with features of Atrophic Rhinitis from infancy & early childhood is reported here. Management of these patients is mainly supportive and otolaryngologist is a vital component of the health care team managing such patients.
