Multiple Metastases of Observed Osteosarcoma Case in A Belgian Malinois Race Female Dog

Abstract

In this study, we aimed to evaluate histopathologically the case of osteosarcoma detected in an Belgian Malinois race dog. The material of the study consisted of a 8.5-year-old Belgian Malinois race female dog weighing 30 kg. With the complaints of abdominal distention, difficulty in breathing, loss of appetite, fatigue, the dog brought to the Veterinary Faculty of Kafkas University Animal Hospital died on the way and was sent to the Department of Pathology for necropsy. In the follow-up, some of the tissue samples taken from the systemic necropsy animal were determined in the decalcified solution and another part in the buffered formaldehyde solution. Following routine procedures, 5 μm thick sections were taken from the prepared paraffin blocks for Hematoxylin Eosin staining. To determine the histopathological changes, the sections were examined by light microscope. In the light of the histopathological findings, osteosarcoma was diagnosed in the brain and lung metastatic foci.
