PROSTATIC CHANGES IN ADULT DOGS NECROPSIED AT THE SCHOOL OF VETERINARY MEDICINE OF THE FEDERAL UNIVERSITY OF GOIAS FROM MAY TO JULY 2004

Abstract

Although prostate changes are common diseases among old dogs, clinical examination of the gland is fre¬quently overlooked in most veterinary clinics. The aim of this study was to describe the microscopic alterations in dog prostates obtained from Zoonosis Control Center of Aparecida de Goiânia, Brazil. Specimens harvested from 50 prostates were embedded in paraffin and sections stai¬ned with H&E. Gram stained fragments were also scre¬ened. Changes were observed in 100% of the cases 31 (62%) animals had prostatitis, 25 (50%) benign prostate hyperplasia, 4 (8%) dysplasia and 1 (2%) adenocarcino¬ma. No bacteria were identified in Gram preparations. As different diseases were occasionally observed in one pros¬tate, the number of processes diagnosed is actually higher than the amount of glands harvested. We concluded that prostate disease is common, particularly in stray dogs, thus prostate examination should be performed as a routi¬ne in dogs, even in the absence of clinical signs, and also that dogs, similar to men, manifest elevated frequency of non-bacterial prostatitis.
