Which is the most common tumor of the parotid gland?

Pleomorphic adenoma (PA), also known as benign mixed tumor, is the most common salivary tumor, constituting up to two-thirds of all salivary gland neoplasms (1). Mostly, PA is located in the parotid glands (85%), minor salivary glands (10%), and the submandibular glands (5%) (2). In the majority of cases, tumors originate in the superficial lobe. However, occasional cases may involve the deep lobe of the parotid gland (3) and the parapharyngeal space. Minor salivary gland tumors are frequently encountered on the palate, followed by the lip, cheek, tongue and floor of the mouth.
