The authors report the cases of two adolescent patients with recurrent respiratory papillomatosis with pulmonary parenchymal spread. Both patients presented very similar initial symptoms and clinical evolution. The patients developed larynx papillomas in childhood causing obstruction to airflow and required permanent tracheostomy after several resection and recurrence episodes. Long time after they developed recurrent pulmonary infections. In both cases the disease was diagnosed through clinical history and high-resolution computed tomography that revealed papillomas in the trachea and solid or cavitary nodules in the lungs.
