Mucoepidermoid carcinoma is the most common malignant tumor of the parotid; however, its synchronous occurrence in both of the parotid glands is extremely rare. Herein, we presented a case of 53-year-old man with bilateral synchronous mucoepidermoid carcinoma of the parotid gland treated with surgery.
The patient mainly complained of a painless mass in the left parotid gland. A mass located in the right parotid gland was incidentally detected by imaging. Based on cytopathology, left total parotidectomy was performed while preserving the facial nerve with ipsilateral neck dissection, and 5 weeks later, right superficial parotidectomy was performed. At the 3-year follow-up, there was no recurrence in the parotid regions and the neck.
A detailed examination for parotid masses is suggested for identifying possible occult synchronous tumors in the contralateral side or in other salivary glands. A close follow-up is also recommended for the risk of future occurrence of metachronous tumors.

Mukoepidermoid karsinom, parotis bezinin en sýk görülen malign tümörü olsa da, her iki bezde eþ zamanlý olarak görülmesi oldukça nadirdir. Bu olgu sunumunda, bilateral parotis bezi mukoepidermoid karsinomuna sahip 53 yaþýnda bir erkek hastanýn taný, tedavi ve takip süreci tartýþýlmýþtýr.
Hastanýn primer þikayeti sol parotis bezindeki aðrýsýz kitleydi. Sað parotis bezindeki kitle ise radyolojik görüntüleme sýrasýnda insidental olarak saptandý. Sitopatolojik inceleme sonrasý, sol tarafa total parotidektomi ve ipsilateral boyun diseksiyonu, sað tarafa ise 5 hafta sonra yüzeyel parotidektomi yapýldý. Hastanýn 3 yýllýk takibinde parotis lojlarýnda ve boyunda rekürrens ya da nüks izlenmedi.
Parotis bezi tümörlerinde, diðer tükrük bezlerinin de detaylý klinik incelemesi, kontralateral bezde ve diðer tükrük bezlerinde eþzamanlý okült tümör olasýlýðý nedeniyle önerilmektedir. Ayrýca, metakron tümör olasýðý nedeniyle, hastalarýn yakýn takibi önemlidir.
