Background: Osteosarcoma (OSA) is a malignant neoplasm of mesenchymal tissue that exhibits various histological features and a differentiated biological clinical behavior.The combination of clinical, radiological, and histopathological features is important for diagnosis. Surgical treatment of neoplasms with pelvic involvement is a challenge.Primary bone tumors are rare in cats and are mostly reported in older animals. The objective of this paper was to report the case of a feline subjected to total hemipelvectomy as primary treatment of pelvic OSA; the surgical technique and histological analysis of the tumor are described.No signs of recurrence were seen during seven months of follow-up. Case: A 4-year-old female mixed breed cat weighing 3 kg was presented with a one year history of increased volume on the hip joint region. Palpation of the increased volume on the hip showed a firm, adhered, and painful mass. Radiographic examination of the pelvis in the dorso ventral projection exhibited a severe osteoblastic bone reaction on the proximal femur, as well as marked periosteal reaction of the hip joint with involvement of the acetabulum. A ventral approach total hemipelvectomy technique was adopted for excision of the tumor. The animal was placed on a lateral position and a circumferential skin incision was performed on the ipsilateral limb of the affected hemipelvis, on the [...](AU)
