Pulmonary Manifestations of Juvenile Laryngotracheal Papillomatosis: Case Report and Literature Review

Abstract

In the present report, we report on a rare case of tracheobronchopulmonary spread of childhood recurrent laryngeal papillomatosis without ana association to prior HPV infection, in a 39-year-old female patient. Recurrent laryngeal papillomatosis (RRLP) is a rare benign disease seen in children and a fewcases are reported in adults. Although RRLP is histologically a benign proliferation of stratified squamous epithelium and is usually limited to the larynx its spread to the tracheobronchial tree occurs in 2% to 29% of cases and to the pulmonary parenchyma in less than 7% of cases.
