Deep-lobe parotid gland tumors.
Fewer than 10% of all parotid gland tumors arise from the deep portion of the gland. The great majority are benign and are mixed tumors. Their clinical presentation in the parapharyngeal space is uncommon, but in the event, the principal differential diagnosis is the elimination of an oropharyngeal primary salivary gland tumor.
