RESUMO
Classification of neoplasms of any organ should be predicted on the patterns of differentiation that reflect the organization and cell types of the parental tissue. The ability to classify a neoplasm instills confidence in its predicted biologic behavior and the selection of treatment. There has not been a single universally used classification system for salivary gland tumor. Histogenetic and morphogenetic concepts and the developing information on various molecular parameters will have significant influence on the classification of salivary glands tumors. In this article we would highlight the histogenetic and morphogenetic concepts in salivary gland neoplasms and elaborate on the taxonomic system of classification of salivary gland neoplasms.
