Öz

Parotis bezinden habis periferik sinir kılıfı tümörü gelişimi son derece nadirdir. Yetmiş altı yaşında erkek hastaya, sol kulak ön-alt bölümünde ülsera- tif kitle nedeniyle daha önce yapılan biyopsi sonu- cunda malign mezenkimal tümör tanısı konmuş, ancak hasta tedaviyi reddetmişti. Sonraki iki ay içinde kitlenin büyümesi nedeniyle parsiyel parotis rezeksiyonu yapılmıştı. Hasta üç ay sonra parotis- te aşırı büyüme nedeniyle kliniğimize başvurdu. Hastaya tedavi olarak total parotidektomi ve radi- kal boyun diseksiyonu uygulandı. Histopatolojik ta- nı malign periferik sinir kılıfı tümörü olarak kondu. Radyoterapi uygulanan hasta beş yıldır takip edilmektedir
