Neuroendocrine Tumor of the Large Intestine in a Dog

This paper describes the diagnosis and treatment of a 5-year-old Standard Schnauzer dog admitted to the clinic due to a liver failure and chronic bloody diarrhea. Based on the initial examination, no diagnosis could be made, therefore an endoscopic examination of the gastrointestinal tract was performed. The endoscopy revealed a tumor within the ostium ileocaecocolicum. Unfortunately, shortly after this procedure, a massive hemorrhage occurred, which led to the animal’s death. The necropsy confirmed the presence of the tumor. The histopathological and immunohistochemical results of the collected specimens showed a neuroendocrine tumor (NET G1) of the large intestine. In conclusion, gastrointestinal carcinoids in dogs are relatively rare and often misdiagnosed due to complex or non-specific symptomatology.

Bir Köpekte Kalın Bağırsak Nöroendokrin Tümörü

Bu makale, karaciğer yetmezliği ve kronik kanlı ishal nedeniyle kliniğe kabul edilen 5 yaşındaki bir Standart Schnauzer köpeğinde nöroendokrin tümör teşhisini açıklamaktadır. İlk muayeneye bağlı tanı konulamadığı için köpeğin gastrointestinal sisteminin endoskopik muayenesi yapıldı. Endoskopik muayenede ostium ileocaecolicum içerisinde bir tümöre rastlandı. Ne yazık ki, bu işlemden kısa bir süre sonra, hayvanın ölümüne yol açan büyük bir kanama meydana geldi. Otopside tümörün varlığı doğrulandı. Alınan örneklerin histopatolojik ve immünohistokimyasal analizi sonucu, kalın bağırsakta bir nöroendokrin tümör (NET G1) belirlendi. Sonuç olarak, köpeklerde gastrointestinal karsinoidler nispeten nadirdir ve karmaşık veya spesifik olmayan semptomatolojisi nedeniyle sıklıkla yanlış teşhis edilirler.
