Parotid gland tumors are usually solitary tumors, and multiple tumors of the parotid gland are extremely rare. We present a highly unusual case of bilateral and simultaneous pleomorphic adenoma and basal cell adenoma of the parotid gland. We review the literature and discuss the clinical manifestations, diagnosis, and treatment of these two rare tumors.
