Lipoid proteinosis of the larynx: a cause of voice change in the infant and young child.

Lipoid proteinosis is an autosomal recessive disorder that may display multiple systemic manifestations involving mucosal deposition of hyalin material. Skin and upper aerodigestive tract mucosal involvement predominate. In approximately two thirds of cases, voice change secondary to laryngeal involvement occurring at birth or early in infancy is the first manifestation of the disease.
