Late presentation of laryngeal lipoid proteinosis: a case report and review of the literature.

Lipoid proteinosis (LP) is a rare autosomal-recessive disease characterized by the deposition of hyaline material infiltrating multiple body organs, including the larynx. The possible clinical presentations are wide-ranging. Laryngeal involvement results in dysphonia that is noted at birth or infantile years. The diagnosis is based on histological findings, and the management options vary depending on the severity of the symptoms. In this paper, we report an unusual case of LP with laryngeal involvement in an adult patient, along with a review of current literature.
