A male Corgi aged 8 years and 9 months is presented with a history of bilateral cryptorchidism.  One of the retained testicles is enlarged and suspected to be neoplastic.  The prostate is also enlarged.  On ultrasound, the prostate is heterogeneous and contains hypoechoic cystic structures. A fine needle aspirate of the prostate is performed and the sample submitted for cytology.
