The aim of this study was to demonstrate the efficacy of FNA technique for the diagnosis of mast cell tumors in dogs. Over one year period all dogs referred to the Veterinary Hospital of the Universidade Federal de Minas Gerais with tumor-like formations of the skin were submitted to FNA. In order to detect metastasis, both skin lesions and the regional lymph nodes were subjected to FNA. After surgical removal of the lesions, histological examination indicated a complete agreement with the cytological diagnosis. In conclusion, FNA technique is a good choice for diagnosis of mast cell tumors in dogs. In addition, FNA allows an adequate and early therapeutic planning.
