In the new 2017 WHO classification, a reduction of the high number of entities of salivary carcinomas was implemented. There is only one new carcinoma entity: secretory carcinoma. There is a slight increase of reactive and benign entities by the inclusion of rare and well-established, but so far not included, lesions. Furthermore, there are some conceptual changes and pure changes in terminology. The impact of molecular findings is increasing and is so far restricted to diagnostic aspects.
