Simultaneous bilateral distinct parotid tumors: a case report / 华西口腔医学杂志

Parotid gland tumors are usually solitary tumors, and multiple tumors of the parotid gland are extremely rare.

We review the literature and discuss the clinical manifestations, diagnosis, and treatment of these two rare tumors.
