Introduction: Synchronous parotid tumors with different histological types account for less than 5% of all salivary gland tumors and the most common combination is Warthin tumor with pleomorphic adenoma. Most lesions detected in salivary glands are benign and unifocal. Ultrasound scans and MRI imaging may not detect separate lesions that are in close proximity and this presents a challenge for radiologists and surgeons in the diagnosis of salivary gland lesions case.
Report: A 61-year-old male patient with right facial swelling since 5 years. Imaging revealed a parotid tumor. FNA shows features of pleomorphic adenoma. On HPE, surprisingly, the 2 tumors with histologically distinct and characteristic histomorphology were revealed. A diagnosis of mixed salivary gland tumor: Pleomorphic adenoma and Warthin›s tumor. Discussion: The incidence of salivary gland neoplasms is 1-2 per 100,000, which is relatively low. The WHO›s classification of salivary gland tumors includes over 30 different types of these tumors. Synchronous tumors of salivary gland are rare with combination of Pleomorphic adenoma and warthin›s tumor being the commonest twins. Surgical treatment with tumor free margins is the treatment method of choice. Conclusion: Benign synchronic tumors of the accessory lobe and the proper parotid are observed rarely. Parotidectomy access is the treatment method of choice when treating large tumors of the accessory lobe.
