Abstract

An 8-year-old female, German Shepherd dog was presented with history of dyspnea and seizure. One Year Previously a lumpectomy had been performed for surgical resection of mammary mass. In serum chemistry, severe hypoglycemia and elevation of aspartate aminitransferase and creatine kinase were shown. In thoracic radiography, there were variable sized nodules in the overall lung field. On computed tomography examination, the mass was shown in left longissimus lumborum muscle. Histopathological examination revealed adenocarcinoma derived from the mammary gland. Muscular metastasis of mammary gland tumor is uncommon. This is a rare observation and could easily be overlooked or misinterpreted.
