Table 7. Benign Salivary Gland Tumors
|BENIGN SALIVARY GLAND TUMORS|
Well-circumscribed; slowly growing; asymptomatic; overlying mucosa is normal unless traumatized; occur only where salivary glands are present (everywhere in the oral mucosa except midline and anterior hard palate, gingiva and attached alveolar mucosa).
|Pleomorphic adenoma (Mixed tumor)||Encapsulated; firm or compressible|
|Monomorphic adenoma||Encapsulated; firm or compressible|
|Oncocytoma||Encapsulated; firm; occurs in older adults|
|Papillary cystadenoma lymphomatosum|
|Encapsulated; firm or compressible; occurs in parotid gland|
|Adenoid cystic carcinoma*||Firm|
|Acinic cell carcinoma*||Firm|
|Mucoepidermoid carcinoma, low-grade*||Compressible or fluctuant|
|Polymorphous low-grade adenocarcinoma*||Firm|
* These are malignant neoplasms, but they sometimes have the clinical & historical features of benign neoplasms.
