Cytology of Skin Neoplasms

Fine-needle aspiration and cytologic examination should be a component of the diagnostic workup of skin masses. Cytologic examination may allow veterinarians to categorize neoplasms of the skin as epithelial, mesenchymal, or round cell and to determine the malignancy potential of the tumor. These results should provide veterinarians the ability to discuss with their clients the subsequent diagnostic considerations and appropriate treatment options for these tumors.
