Abstract

A case of laryngeal squamous papilloma in the early stages of development showed histological features suggestive of virus infection. Five years later positive evidence of HPV-6 infection was obtained at a time when the lesion had developed into a squamous cell carcinoma. It is concluded that this case represents a complete example of the virus to papilloma to carcinoma sequence, and as far as is known, is the first reported case of its kind in the larynx.
