Abstract
A twelve-year-old, intact female maltese was brought to us with anorexia from one day before, and CBC, biochemistry, radiography, and ultrasonography showed polycythemia and right-sided renomegaly. Surgical removal of the right kidney was not done, because bilateral renal masses were found, and only a biopsy was performed. The renal masses were diagnosed as lymphoma. The dog was treated with multidrug combination chemotherapy, which improved polycythemia and anorexia for a while. On day 78, polycythemia recurred, and abdominal ultrasonography revealed lymphadenopathy. In spite of medication with lomustin, the polycythemia gradually worsened. The dog died on day 146. Canine renal lymphoma is a very rare disease.
