| Abstract: | Undifferentiated malignant tumors of the oral cavity were diagnosed in six dogs under 2 years of age. The dogs were examined because of pain and swelling of the upper molar or premolar areas. In all six dogs, the tumors were initially misdiagnosed as infections or carnasal abscesses. The differential diagnosis included malignant lymphoma, osteosarcoma, mesenchymal chondrosarcoma, embryonal rhabdomyosarcoma, and malignant melanoma. Electron microscopy of three neoplasms showed that there were no specific features characteristic of carcinoma or sarcoma. Immunoperoxidase studies for cytokeratins, epithelial membrane antigen, actin, myosin, desmin, and vimentin were also negative. We conclude that these tumors be designated undifferentiated malignant tumors of the oral cavity until histogenesis is established. © 1986, American College of Veterinary Pathologists.
