The diagnosis is made by cytopathological analysis and classified by means of histopathology. Treatment is based on staging, surgical exeresis with antineoplastic chemotherapy and drug treatment to inhibit the effects of histamine release. A dog of 14 years old of Boxer breed was attend complaining of nodulation in the testicular bag with a two month evolution. Animal was diagnosed with mast cell tumor. Treatment was instituted by surgical excision and due to the metastatic possibility in regional lymph node, antineoplastic and drug therapy was indicated, which was not successful due of the person responsible non-adherence to the treatment.
