Canine testicular tumours: a study on 232 dogs.
The aim of this study was to provide an up-to-date estimate of the prevalence of canine testicular tumours, an earlier study (reported in 1962) having found a prevalence of 16%. Histological examination of both testes collected at necropsy from 232 dogs revealed that 62 (27%) had one or more testicular tumours, the total number of tumours identified being 110. Of these, 55 were interstitial cell tumours, 46 were seminomas, and nine were Sertoli cell tumours. The results suggest that, as reported in man, testicular tumours in dogs have increased during the past 40 years. Further studies should investigate the possible causative role of environmental pollutants.
