[Tracheobronchial and pulmonary papillomatosis without involvement of the larynx treated with intravenous Bevacizumab in a child].

Recurrent respiratory papillomatosis is an infrequent benign neoplasm that commonly affects the upper airway with a predilection for the larynx. Isolated tracheobronchial involvement is very rare. Diagnosis and treatment of this disease is a challenge due to its non-specific clinical manifestation and its recurrent nature. We present a 6-year-old male with a diagnosis of asthma refractory to treatment, without history or evidence of laryngeal papillomatosis. The endoscopic examination revealed extensive tracheobronchial papillomatosis and the computed tomography, pulmonary involvement. He received adjuvant therapy with intravenous Bevacizumab with very good response. We alert pediatricians to consider this rare tracheobronchial neoplasm in all children with atypical asthma symptoms or in those who do not improve with conventional medical treatment.
