A 39-year-old man had three coexistent neoplasms of the larynx, squamous papilloma, verrucous carcinoma, and squamous carcinoma. In our review of the English literature, we could not find a similar case report. The potential transformation of benign laryngeal papilloma to verrucous carcinoma and infiltrating squamous cell carcinoma is discussed.
