Coexisting benign mixed tumor and mucoepidermoid carcinoma of the parotid gland.

Multiple unilateral parotid gland tumors are very rare. A review of the literature shows only seven cases of coexisting unilateral parotid tumors. This patient had a benign mixed tumor and a mucoepidermoid carcinoma of the right parotid gland. This is the eighth reported case of multiple unilateral parotid tumors and the first to show such a combination of tumors.
