[Bronchoscopic Interventional Treatment of Mixed Squamous Cell and Glandular 
Papilloma of Diffuse Trachea: A Case Report and Literature Review].

Pulmonary mixed squamous cell and glandular papilloma (MSCGP) is a subtype of pulmonary papilloma, which can be classified as central type and peripheral type based on its site of development. The central type is the most common. The clinical manifestations of pulmonary MSCGP are mainly related to the location of the tumor. Surgery is the main treatment for this disease. Bronchoscopic interventional treatment for the MSCGP in the central trachea could receive satisfactory effect. We reported a patient suffered from diffuse tracheal MSCGP who was treated by bronchoscopic interventional treatment in Respiratory Disease Center, Dongzhimen Hospital of Beijing University of Chinese Medicine, aiming to enhance the recognition of the clinical features and provide clinical references for the diagnosis and treatment of such disease.
