Solitary mixed type papilloma in trachea : a case report and literature review

Solitary papilloma in the respiratory system is thought to be a rare benign epithelial tumor, and complete surgical resection is currently the standard treatment for this type of tumor. We report a case of solitary mixed-type tracheal papilloma treated with a snare under a tracheoscope. Tracheal papilloma is rare, and mixed-type papilloma is rarer. The patient’s clinical manifestations were recurrent cough. After removal of the tumor by using a snare under bronchoscopy, the patient’s cough resolved. No recurrence was observed in the following 3 months after the treatment. No complications occurred during the treatment. Mixed-type tracheal papilloma in adults can be clearly diagnosed using bronchoscopy. Local excision is thus recommended for solitary mixed-type tracheal papilloma.
