Abstract

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

Abstract

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.
