Squamous cell papillomas are the most common benign tumors of the larynx (1). A solitary bronchial squamous cell papilloma (BSCP) was first reported in 1954 (2). BSCP is a benign tumor originating from squamous cell epithelium cells, and it accounts for 0.38% of all lung tumors (3). There are two primary clinical features of bronchial papillomas.
