Due to diverse nature of salivary gland neoplasms, many different terms and classification systems have been used. Perhaps the most widely used currently is that system proposed by the World Health Organization in 2004, which classifies salivary neoplasms as primary or secondary, benign or malignant, and also by tissue of origin. This system defines five broad categories of salivary gland neoplasms:<ref name="wiki">  Salivary gland neoplasm.

Overview

Salivary gland tumor may be classified according to the World Health Organization into five groups: malignant epithelial tumors, benign epithelial tumors, soft tissue tumors, hematolymphoid tumors, and secondary tumors.[1]

Classification

Due to diverse nature of salivary gland neoplasms, many different terms and classification systems have been used. The World Health Organization in 2004, classified salivary neoplasms as primary or secondary, benign or malignant, and also by tissue of origin. This system defines five broad categories of salivary gland neoplasms:[1]

Malignant epithelial tumors

Benign epithelial tumors

Soft tissue tumors

Hematolymphoid tumors

Secondary tumors

Secondary tumor is a tumor which has metastasized to the salivary gland from a distant location.

Tumors not included in the WHO classification above, include:

Hybrid tumor is a tumor displaying combined forms of histologic tumor types.
  • Hybrid carcinoma
  • Others
  • Others
    • Keratocystoma
    • Sialolipoma
