- Benign lymphoepithelial lesion: 1%
- Oxyphil adenoma, oncocytoma, and other rare lesions:< 1% each

In the parotid region, the presence of pain, rapid enlargement of a nodule, skin involvement, or facial nerve paralysis is highly suggestive of a malignancy. - Mucoepidermoid carcinoma: 44% (the low-grade variety of this tumor is "almost benign")
- Malignant mixed tumor: 17%
- Acinic cell carcinoma: 17%
- Adenocarcinoma: 10%
