Salivary gland neoplasm

Salivary gland cancer is a cancer that forms in tissues of a salivary gland. The salivary glands are classified as major and minor. The major salivary glands consist of the parotid, submandibular, and sublingual glands. The minor glands include small mucus-secreting glands located throughout the palate, nasal and oral cavity. Salivary gland cancer is rare, with 2% of head and neck tumors forming in the salivary glands, the majority in the parotid.
==Classification==
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:
* Malignant epithelial tumors
*
* Acinic cell carcinoma
*
* Mucoepidermoid carcinoma
*
* Adenoid cystic carcinoma
*
* Polymorphous low-grade adenocarcinoma
*
* Epithelial-myoepithelial carcinoma
*
* Clear cell carcinoma, not otherwise specified
*
* Basal cell adenocarcinoma
*
* Sebaceous carcinoma
*
* Sebaceous lymphadenocarcinoma
*
* Cystadenocarcinoma
*
* Low-grade cribriform cystadenocarcinoma
*
* Mucinous adenocarcinoma
*
* Oncocytic carcinoma
*
* Salivary duct carcinoma
*
* Salivary duct carcinoma, not otherwise specified
*
* Adenocarcinoma, not otherwise specified
*
* Myoepithelial carcinoma
*
* Carcinoma ex pleomorphic adenoma
*
* Carcinosarcoma
*
* Metastasizing pleomorphic adenoma
*
* Squamous cell carcinoma
*
* Large cell carcinoma
*
* Lymphoepithelial carcinoma
*
* Sialoblastoma
* Benign epithelial tumors

*
* Hodgkin lymphoma
*
* Diffuse large B-cell lymphoma
*
* Extranodal marginal zone B cell lymphoma
* Secondary tumors (i.e. a tumor which has metastasized to the salivary gland from a distant location)
Others, not included in the WHO classification above, include:〔
* Intraosseous (central) salivary gland tumors
* Hybrid tumors (i.e. a tumor displaying combined forms of histologic tumor types)
*
* Hybrid carcinoma
*
* Others
* Others
