Abstract

Epithelial-myoepithelial carcinomas are rare, low- grade, malignant salivary gland tumors. They are mostly seen in the parotid gland. The submandibular gland is a rare localization. A 54-year-old woman presented with a painless lump on the left side of the neck. Examination showed a mass with smooth sur- face in the left submandibular region. Fine needle aspiration cytology of the mass was reported as malignant epithelial tumor metastasis. Computed tomography of the neck showed left submandibular gland hypertrophy. Left submandibular gland exci- sion with functional neck dissection was performed.The histopathological diagnosis was epithelial- myoepithelial carcinoma of the submandibular gland with one lymph node metastasis. Postoperative radiotherapy was administered. There was no evi- dence for recurrence during a two-year follow-up.

Submandibuler bezde epitelyal-miyoepitelyal karsinom: Olgu sunumu

Abstract

Epitelyal-miyoepitelyal karsinomlar nadir görülen, malign karakterli, düşük dereceli tükürük bezi tümör- leridir. En sık parotis bezinde görülen bu tümörlerin submandibuler bezde gelişimi nadirdir. Boyun sol ta- rafında ağrısız şişlik yakınmasıyla başvuran 54 ya- şındaki kadın hastanın KBB muayenesinde sol sub- mandibuler bölgede düzgün yüzeyli şişlik saptandı. Bu şişlikten yapılan ince iğne aspirasyon sitolojisi malign epitelyal tümör metastazı olarak bildirildi ve boyun tomografisinde sol submandibuler bezde bü- yüme saptandı. Hastaya sol submandibuler bez ek- sizyonu ile birlikte fonksiyonel boyun diseksiyonu ya- pıldı. Histopatoloji sonucu submandibuler bezin epi- telyal-miyoepitelyal karsinomu olarak bildirilen ve bir adet lenf nodu metastazı saptanan hastaya ameliyat sonrası radyoterapi uygulandı. İki yıllık takiplerde hastada herhangi bir nükse rastlanmadı
