Clinical and histopathological evaluation of bovine ocular and periocular neoplasms in 15 cases in sanliurfa region

Sunulan çalışmada; sığırlarda tespit edilen göz tümörlerinin klinik ve histopatolojik karakterleri ile uygulanan sağaltım sonuçlarının değerlendirilmesi amaçlandı. Çalışmanın materyalini cerrahi kliniğine 2008-2011 yılları arasında getirilen veya mahallinde müdahalesi yapılan, modern çiftlik ya da ev ahırlarında barındırılan oküler-perioküler tümörlü 15 sığır oluşturdu. Tedavi amacıyla, 5 vakada lokal tümör ekstirpasyonu, 10 olguda göz ekstirpasyonu uygulandı. Post operatif dönemde tüm vakaların, bir ay süreyle haftalık kontrolleri ve yara bakımları yapıldı. Post operatif, ortalama 6. aya kadar telefonla hasta sahibinden bilgi alınmaya çalışıldı. Uzaklaştırılan 15 tümöral kitlenin histopatolojik muayeneleri sonucunda; 11 (%73)’inin yassı hücreli göz kanseri, 1 (%7)’inin trikoepitelyom, 1 (%7)’inin solid tip apokrin duktal karsinom, 1 (%7)’inin apokrin karsinom ve 1 (%7)’inin de fibrosarkom olduğu tespit edildi. Post operatif 6. aya kadar tümörlerin nüks etmesi veya muhtemel bir metastaz ile ilgili net bir bulguya rastlanılamadı. Bir vakada bir ay süren parotit lenf bezi şişkinliği ve 1 vakada tedaviye cevap veren orbital enfeksiyon gözlendi. Belirtilen takip süresi içerisinde, uygulanan tedavilerin 15 vakada başarılı olduğu, önceden belirtilen süt ve kilo kaybının da büyük oranda düzeldiği gözlendi. Sonuç olarak; sığırların oküler-perioküler dokularında oluşan değişik karakterdeki tümörlerinde uygulanan lokal tümör rezeksiyonu veya total göz ekstirpasyonu gibi tedavilerin, kolay uygulanabilir, az komplikasyon riskli ve düşük maliyetli olduğu söylenebilir. Aynı zamanda, kronik ağrıyı ortadan kaldırması sonucu, hayvanların ekonomik ömrünün uzaması ve dolayısıyla ekonomik kayıpların minimize edilmesi nedeniyle uygun bir yöntem olabileceği düşüncesine varıldı.

Şanlıurfa yöresinde sığır oküler ve perioküler tümörlerinin klinik ve histopatolojik olarak değerlendirilmesi: 15 olgu

The present study was conducted to evaluate the clinical and histopathological characteristics of bovine ocular and periocular neoplasms and the results of the therapeutic procedures. The study materials were 15 cattle with ocular-periocular neoplasms, which were housed at modern farm premises or family holdings and either referred to the surgery clinic or treated on-site, between 2008-2011. Treatment was performed by local tumour extirpation in 5 cases and ocular extirpation in 10 cases. In the post operative period, routine controls and wound care were performed on a weekly basis for a one month period in all of the cases. Furthermore, efforts were made to obtain information from the animal owner up to the 6th month post-operation. Based on the histopathological examination of the extirpated neoplastic tissues, 11 of the cases (73%) were diagnosed with ocular squamous cell carcinoma, whilst 1 case (7%) each was diagnosed with trichoepithelioma, solid apocrine ductal carcinoma, apocrine carcinoma, and fibrosarcoma. Until the 6th month post-operation no finding that would suggest the recurrence or possible metastasis of the neoplasms has been observed. In one of the cases, swelling of the parotid lymph node, which lasted for one month, was encountered, whilst another case presented with orbital infection that responded to treatment. During the follow-up period, it was observed that, the therapeutic procedures succeeded in all 15 cases, and decreased milk yields and weight loss improved to a large extent. In conclusion, local tumour extirpation and total extirpation of the eye performed for the treatment of various neoplasms that occur in ocular and periocular tissues are readily applicable and inexpensive methods with low complication risk. Furthermore, these methods are considered feasible as they maintain the economic life of animals and minimize economic losses through the relief of chronic pain.
