Use of cryotherapy to treat obstructing papilloma of an accessory tracheal bronchus: case report

BACKGROUND: Tracheal papillomatosis is a relatively rare condition with limited data on successful treatment modalities. To our knowledge, this is the first report to describe a papilloma arising from an accessory bronchus. Furthermore, this case report demonstrates successful treatment with clinical and patient-centered improvements after use of Spray Cryotherapy. CASE PRESENTATION: A 71-year-old woman presented with one year history of recurrent fevers and intermittent hemoptysis. Imaging and video bronchoscopy revealed an obstructing papilloma of an accessory tracheal bronchus to the right upper lobe. She was treated with debridement followed by multiple cryotherapy treatments resulting in complete clinical and radiographic resolution of her post-obstructive pneumonia. CONCLUSIONS: This case report not only supports existing literature on the use of cryotherapy for airway diseases but also presents a unique form of obstructing papilloma confined to an accessory bronchus, the only report of its kind based on extensive literature review.
