A clinicopathologic and ultrastructural study of undifferentiated malignant tumors of the oral cavity in dogs

, : A clinicopathologic and ultrastructural study of undifferentiated malignant tumors of the oral cavity in dogs. Veterinary Pathology 23(2): 170-175

Undifferentiated malignant oral tumours were diagnosed in 6 dogs under 2 years of age examined for pain and swelling of the upper molar or premolar areas. In all 6 the tumours were initially misdiagnosed as infections or carnasal abscesses. Electron microscopy of 3 neoplasms showed no specific features characteristic of carcinoma or sarcoma. Immunoperoxidase studies for cytokeratins, epithelial membrane antigen, actin, myosin, desmin, and vimentin were negative.
