Sığırlarda Oküler ve Perioküler Tümörlerin Klinik ve Histopatolojik Değerlendirilmesi

Bu çalışmada oküler ve perioküler tümörlü 9 sığırın klinik ve histopatolojik özellikleri ile uygulanan eksizyon ve enüklasyon sonuçlarının değerlendirilmesi amaçlandı. Tedavi amacıyla 4 vakada lokal tümör eksizyonu ve 4 vakada göz enüklasyonu uygulanırken 1 vakada bulbus okuli ve çevre dokulardaki geniş tümör invazyonlarından dolayı kesime sevk önerildi. Histopatolojik muayenede 4 vakada yassı hücreli kanser, 2 vakada indiferensiye yassı hücreli kanser, 1 vakada melanom ve 2 vakada malign melanom tespit edildi. Oküler ve perioküler tümörlerin farklı ırklarda görülmesine rağmen en fazla Holstein ırkında karşılaşıldığı saptandı. Ayrıca vakaların çoğunun yassı hücreli kanser olması da dikkat çekti. Etkilenen hayvanların tamamının dişi ve ortalama yaş aralığının 4.78 olduğu gözlendi. Opere edilen hayvanlar ortalama 6 aya kadar takip edildi ve nüks veya metastaz yönünden net bir bulguyla karşılaşılmadı. Sonuç olarak oküler ve perioküler tümörlerin tedavisinde eksizyon ve enüklasyon maliyeti düşük, basit ve az ekipmanla kolay uygulanabilir cerrahi yöntemlerdir. Ayrıca bu yöntemlerin oküler ve perioküler tümörlerde ağrıyı azaltmak, hayvanın yaşam kalitesini yükseltmek, verim süresini arttırmak ve ekonomik kayıpları azaltmak amacıyla kullanılabileceği gösterilmiştir.

Clinical and Histopathological Evaluation of Bovine Ocular and Periocular Tumors

In this study, we aimed to evaluate clinical and histopathological features and the results of applied excision and enuclation of ocular and periocular tumors in 9 cattle For treatment purposes, local excision of the tumor in 4 cases and eye enucleation in 4 cases were applied. In one case, slaughter was recommended because of the extensive tumor invasion of bulbus oculi and surrounding tissues. Squamous cell carcinoma in 4 cases, indifferential squamous cell carcinoma in 2 cases, melanoma in 1 case and malign melanoma in 2 cases were detected in the histopathological examination. Although the ocular and periocular tumors are seen in different breeds, it was noted that they were most encountered in Holstein breed. It was also noticed that the majority of the such cases were squamous cell carcinomas. It was observed that the entire affected animals were female and average age range was 4.78 years. Operated animals were followed approximately up to six months and no recurrence or metastasis was encountered during period. In conclusion, excision and enuclation in the treatment of ocular and periocular tumors are surgical methods that are simple, with low cost and easily performed with less equipment. In addition, these methods can be used to reduce of pain, improve the quality of life of the animal, increase the yield period and reduce economic losses in ocular and periocular tumors.
