Removal of a multilobular osteosarcoma in a 9 year old Labrador Retriever

Author
DiLorenzo, Scott
Abstract
A 9 year old, male castrated Labrador Retriever presented to Cornell University Veterinary
School with a firm, fixed mass of the right zygomatic arch. Cytologic evaluation revealed this to be a mesenchymal neoplasm. Computed tomography studies were performed and showed the
extensive local involvement of this mass with the calvarium. The owner opted for surgical
removal of the mass. A dorso‐lateral approach was used to obtain best visualization of the
lesion intra‐operatively. The mass, along with the right zygomatic arch, right eye and
associated structures, caudal maxilla, and 2 molars were removed. The patient recovered
uneventfully from surgery. Histopathology of the mass came back as a multilobular tumor of
bone.
