Prostate as sole unusual recurrence site of lymphoma in a dog.
A ten-year-old intact male Rottweiler dog was examined for sudden onset of stranguria and pollakiuria. The dog had an intestinal lymphoma treated three years before with chemotherapy. Ultrasonographic examination of the abdomen showed a large dyshomogeneous prostate with an over-distended bladder. Cytological examination of the fine-needle aspirate from the prostate yielded a diagnosis of lymphoma. The diagnosis was confirmed by histopathological examination. The dog was treated with multi-drug chemotherapy and achieved a complete remission. The dog remained in complete remission for one year from the re-institution of chemotherapy before dying of recurrence. Lymphoma rarely invades the prostate in the dog. To the best of our knowledge this is the first report of prostatic recurrence of lymphoma in a canine patient originally affected by intestinal lymphoma and treated with chemotherapy.
