Oral verrucous carcinoma.

Verrucous carcinoma is a well-defined variant of the squamous cell carcinoma. Although it is reported to be rare in the Scandinavian countries, 16 cases have been diagnosed in the Southern part of Norway from 1975 to 1982. The clinical and histological characteristics were investigated. The most common site of occurrence was the mandibular alveolar ridge. The average age was 71 years, and unlike most other series of verrucous carcinoma, there was a female predominance and use of tobacco seemed to be the exception. The patients mainly complained of ill-fitting dentures. Adequate surgical excision appears to be the treatment of choice.
