title: [Verrucous carcinoma of the nasal cavity: a case report].
abstract: We report a rare case of verrucous carcinoma occurring in the nasal cavity. A 53-year-old man reporting left-sided nasal obstruction and awareness of a left intranasal lesion--a whitish polypoid lesion--was found in CT to have an expansive lesion of the left nasal cavity and maxillary sinus. The tumor was completely removed by Denker's operation. Verrucous carcinoma is a rare variant of squamous cell carcinoma most commonly seen in the oral cavity. In some cases, conventional squamous cell carcinoma components may be observed focally in verrucous carcinoma, called a hybrid tumor. In our case, the tumor showed typical features of a hybrid tumor. To the best of our knowledge, this is the first case of hybrid verrucous squamous cell carcinoma originating in the nose in the Japanese literature.
