Solitary Squamous Papilloma of Trachea-A Case Report

Squamous papilloma is a benign lesion commonly found on orolaryngeal mucosa and may be associated with HPV type 6 and 11, but is seldom described as a tracheobronchial tumor especially the solitary form. We presented a 39-year-old man with history of laryngeal papillomatosis who suffered from solitary endotracheal squamous papilloma. The endotracheal lesion was pedunculated and about 0.9 cm in size, and resulted in obstruction of the airway. He underwent flexible bronchoscopic Nd-YAG laser ablation under local anesthesia without intubation. This was a rare case based on a literature review since it was a solitary form of endotracheal tumor that underwent bronchoscopic laser ablation without intubation. The clinical manifestations and treatment of these tracheobronchial papillomas are reviewed.
