  39. Papillomatosis KANKER- 2013-pts

  40. Epuloides • Acanthomatous epulis • Histologic appearance • Highly cellular • Interconnecting odontogenic epithelial sheets bordered by columnary to cuboidal cells • Contain numerous, usually empty, blood vessels KANKER- 2013-pts

  41. Other tumors of dental origin • Less common than epuli • Ameloblastoma • Dental lamina • Outer enamel epithelium • Odontogenic epithelium • May produce dentin or enamel matrix • Rare in all species, but less rare in cattle • Young cattle KANKER- 2013-pts

  42. Other tumors of dental origin • Complex odontoma • Fully differentiated dental components • Disorganized, no tooth like structures • Young horses • Compound odontoma • Mass containing numerous tooth-like structures • “denticles” • Young dogs, cattle, and horses • Mandibular or maxillary arch KANKER- 2013-pts

  43. Oral tumors of non-dental origin • Squamous cell carcinoma • Most common oral neoplasm is cats • Ventral surface of the tongue, along the frenulum • Nodular, red-grey mass • Friable • Often ulcerated • Locally invasive • Metastasize to regional lymph nodes • Rarely metastasize to lung KANKER- 2013-pts

  44. Fibrosarcoma • Gross appearance • Nodular to multi-nodulare • +/- ulceration • Firm • Local invasion • ~ 35% metastasize to lymph nodes • Early pulmonary metastasis KANKER- 2013-pts

  45. Osteosarcoma • Bones of the skull or jaw • Similar in appearance to fibrosarcoma • Bone lysis and proliferation on radiographs KANKER- 2013-pts

  46. Round cell tumors • Mast cell tumors • Discreet mass • Lymphosarcoma • Tonsillar • Epitheliotrophic • Plasma cell tumors • Discreet mass • Pleomorphic plasma cells KANKER- 2013-pts
