Aggressive osteoblastoma of the cervical vertebrae in a Turkish Angora cat

Aggressive osteoblastoma is a type of bone tumor rarely reported in veterinary literature. Osteoblastoma may be misdiagnosed as an osteosarcoma, which is a well-understood malignant bone tumor. Owing to poor prognosis, animals diagnosed with osteosarcoma are not always treated. In the present case, we diagnosed the tumor as aggressive osteoblastoma on the basis of macroscopic, microscopic, radiographic, and immunohistologic findings. The patient was treated via resections of the osteoblastoma and lived without metastasis for 3 years. This is the first reported case of aggressive feline osteoblastoma of the cervical vertebrae and will be useful for diagnosing and managing aggressive osteoblastoma.
