Abstract

İki aydır süren tek taraflı periorbital şişlik, blefarospazm ve şiddetli kanama şikayetiyle fakülte kliniklerine getirilen 34 yaşlı bir Afrika gri papağanında (Psittacus erithacus), üçüncü göz kapağının (niktitan membran olarak da bilinen) skuamöz hücreli karsinomu (SCC) teşhis edildi. Genel anestezi altında, üçüncü göz kapağı membranının bulbar yüzeyinde, göz küresinin bulbar konjunktivasının ventromedial kadranına bağlı büyük, sert, sarı bir kitle tespit edildi. Kitle cerrahi olarak eksize edildi, ancak operasyondan hemen sonra kuş öldü. Kuş ve sol göz küresi adneksal yapılarıyla birlikte histopatolojik incelemeye gönderildi. Kitle 0.8x1 cm boyutlarındaydı ve histopatolojik incelemede SCC olduğu belirlendi. Göz küresi ve vücudun diğer organlarında metastaz görülmedi.

Squamous Cell Carcinoma of the Third Eyelid Membrane in an African Grey Parrot (Psittacus erithacus)

Abstract

Squamous cell carcinoma (SCC) of the third eyelid membrane (also known as the nictitating membrane) was diagnosed in a 34-year-old African grey parrot (Psittacus erithacus) that was presented to the clinics of our faculty for unilateral periorbital swelling, blepharospasm, severely bleeding of 2 months duration. A large, hard, yellow mass on the bulbar surface of the third eyelid membrane that was attached to the ventro-medial quadrant of the bulbar conjunctiva was identified under general anesthesia. Surgical removal of the mass was performed but the bird died just after the operation. The left globe with adnexal tissues and the body of bird were submitted for histopathological examination. The dimensions of the solitary mass were 0.8x1 cm and the histopathological examination revealed SCC. There was no evidence of metastasis in the globe and other organs.
