Pleomorphic adenoma is the most common parotid gland tumor. It accounts for  70-80% of all benign parotid tumors.

Over 84% of pleomorphic adenomas occur in the parotid gland, 8% occur in the submandibular gland, and 6.4% occur in the minor salivary glands.

Pleomorphic adenomas are usually seen in middle aged women and present as a painless slowly growing mass.  Typically, these masses are solitary and well demarcated. They may appear heterogeneous secondary to hemorrhage, calcification, and necrosis.

Sarcomatous transformation is seen in only 2-5% of cases and is usually associated with tumors that have been present for 10-15 years.
