Parotis bezinde epiteliyal-miyoepiteliyal karsinom: Olgu sunumu

Epiteliyal-myoepiteliyal karsinom tüm tükürük bezi neoplazmlarının yaklaflık %1’ni oluflturur. Tümörle- rin çoğu majör tükürük bezlerinden, özellikle de pa- rotis bezinden kaynaklanır. Epiteliyal-myoepiteliyal karsinomlu 65 yaflındaki erkek hastanın manyetik rezonans görüntülemesinde sol parotis bezinde dü- zensiz ve heterojen kitle görüldü. Hastaya yüzeysel parotidektomi uygulandı. Yirmi bir aylık takip süre- sinde herhangi bir komplikasyon ya da nüks saptanmadı.

A case of epithelial-myoepithelial carcinoma of the parotid gland

Epithelial-myoepithelial carcinomas comprise approximately 1% of ali salivary gland neoplasms. Most tumors arise in the majör salivary glands, especially in the parotid gland. We present a case of epithelial- myoepithelial carcinoma of the parotid gland in a 65- year-old male patient. Magnetic resonance imaging showed an irregular and heterogeneous mass in the left parotid gland. Superficial parotidectomy was per- formed. There was no evidence of recurrence during a 21-month follow-up.
