Bir Köpekte Kondrosarkom Olgusu

Bu çalışmada altı yaşında, erkek, kurzhaar cinsi bir köpekte kostal yayılımlı kondrosarkom olgusu tanımlandı. Klinik muayenede göğüs bölgesinin sol tarafında, kostalar üzerinde saptanan tümör kitlesi total olarak ekstirpe edildi. Makroskobik muayenede tümör olarak değerlendirilen kitle 16x10x4 cm boyutlarında ve 280 g ağırlığında ölçüldü. Tümör kesit yüzeyi kirli beyaz renkte, granüler yapıda ve özellikle kitlenin merkezi akışkan bir görünümdeydi. Mikroskobik olarak, yüksek derecede hücresellik, nükleer atipi, mitoz gösteren hücreler ile birlikte, kondroid bir stroma ve lakünler içerisinde birden çok çekirdekli belirgin pleomorfizm gösteren hücreler görüldü. Olgu makroskopik ve mikroskobik bulgulara göre kondrosarkom olarak teşhis edildi. Ender olarak görülen bir tümör tipi olması sebebiyle bu olgunun, klinik ve histopatolojik yönden değerlendirilmesi ve raporlanması düşünüldü.

A Case of Chondrosarcoma in a Dog

Tumor section was dirty white surface, granular structure and especially the center of the mass was in viscous appearance. In microscopic exam; high cellularity, nuclear atypia, mitotic cells, a chondroid stroma and multi-nucleus cells showing clear pleomorphism in the lacunaes were seen. According to the macroscopic and microscopic findings the case was diagnosed as chondrosarcoma.
