AIM:Salivary gland tumors account for 2% to 6.5% of all head and neck neoplasms, are more common in women with a peakincidence in their 60s and 70s, but can occur in all age groups. The majority of neoplasms occur in parotid, and pleomorphicadenoma is the most common benign tumor. There is a slight male predilection and, although PAs can occur in any age, theyare more common between the 40s and 50s. The aim of this study that presentation of some common benign tumor isoccurred in parotid gland and presentation of their surgical operation.

CASE:We would like to presentate different three cases those, first is pleomorphic adenoma, second is Warthin's tumor, thirdis oncocytomas. Pleomorphic adenoma demonstrate pleomorphic patterns of various ratios of epithelial and mesenchymalelements and are enclosed in a connective tissue pseudocapsule. The lack of true capsule, the deficiencies of thepseudocapsule, and the tumor extensions through these defects are thought to contribute to recurrences. Two neoplasmsmake up the subcategory of oncocytic tumors: Warthin’s tumor (or papillary cystadenoma lymphamatosum) and oncocytoma,due to presence of oncocyticappearing epithelial cells or proliferation of oncocytic cells. Warthin’s tumor accounts for 5% to 7%of epithelial salivary gland neoplasms, with the vast majority found in the parotid, with bilateral involvement in 4% to 6% of thecases. There is a 3:1 male-to-female predilection; patients affected are between 30 and 70 years; and this tumor is associatedwith cigarette smoking. Similarly, oncocytomas are small tumors found in the parotid. Although well encapsulated, theseneoplasms may demonstrate multinodularity.

CONCLUSION:Surgical excision is the treatment of choice for those tumors. Superficial parotidectomy with preserving facialnerve is preferred generally. However, take care of adequate removal when tumor excision with capsule or pseudocapsule forpreventing recurrences.
