Solitary tracheo-bronchial papillomas are rare benign neoplasms. They are subclassified into three categories by variety of histological cell types including squamous cell papilloma, glandular papilloma and mixed squamous cell and glandular papilloma. Of these types, mixed squamous cell and glandular papilloma is extremely rare and a few cases reported in Korea. We describe a case of mixed squamous cell and glandular papilloma arising from the upper trachea with a review of the relevant literature. To our knowledge, this is the first reported case of upper tracheal mixed squamous cell and glandular papilloma in Korea. (J Clinical Otolaryngol 2013;24:305-310)
