Oral carcinomas associated with snuff dipping. Some clinical and histological characteristics of 23 tumours in Swedish males

Abstract

Some clinical and histological characteristics of 23 oral carcinomas in the anterior vestibulum of snuff dipping Swedish males with an average age of 76 yr were investigated. Examples of verrucous carcinomas, as well as of ordinary, usually verrucoid but also ulcerating, squamous cell carcinomas, were encountered. Widespread oral leukoplakia and 2nd primary carcinoma, oral or other, was present in 5 and 6 cases, respectively and occurred together in 3 of these. Eleven cases out of 19 available for additional sectioning and staining showed candidal infection.
