title: Synchronous unilateral parotid neoplasms. A case report.
abstract: The parotid gland is the most usual location of benign neoplasms affecting major salivary glands and quite often the recurrence of these tumours is noticed, specially in the case of pleomorphic adenoma. The occurrence of multiple tumours in the parotid glands is rare and the majority of these are multifocal Warthin's tumors (papillary cystadenoma lymphomatosum). The simultaneous development of tumours with different histological types is unusual and when it occurs, the most common combination is a pleomorphic adenoma and a Warthin's tumor. There are many articles about Multiple Parotid Tumors (MPT) but only a few of them are focused on unilateral synchronous benings tumors, being pleomorphic adenoma and Warthin's these tumors. The report describes a 55 year old female with a pleomorphic adenoma occurring synchronously with a Warthin's tumor within the superficial lobe of her left parotid gland.
