Presence of cystic endometrial hyperplasia and uterine tumours in older pet pigs in the UK

Experience in farm animal referral centres in the UK has shown an increase in the number of pigs being presented for age related problems. These include obesity, arthritis, skin disorders, overgrown tusks and overgrown claws. Seven pigs presented over a seven year period to two university veterinary teaching hospitals in the UK with clinical signs including behavioural change, excessive vaginal discharge, inappetence and abdominal distension which were found to localise to the reproductive tract. Histology of the reproductive tract found cystic endometrial hyperplasia (n=7) and uterine tumours (n=4) following ovariohysterectomy (n=4) or post-mortem examination (n=3). Tumours identified were leiomyoma (n=1), fibroleiomyoma (n=1) and leiomyosarcoma (n=2).
