[Uterine neoplasia in two geriatric miniature pet pigs - diagnostics and therapy. Two case reports]

Miniature pet pigs are becoming ever more common among the patients of small animal practices. Due to an advanced age attained in these animals in comparison with conventional pigs in pork production, miniature pet pigs develop age-related diseases that are infrequently observed in farm pigs, including neoplastic alterations of the uterus. We describe two cases of a uterine adenocarcinoma and a leiomyoma, respectively, in two miniature pet pig sows. Options and limits of diagnostic measures (unspecific clinical symptoms, x-ray, sonography and computed tomography) and therapy within the legal limits as well as the risk of an incorrect diagnosis based upon the more common differential diagnoses in swine medicine, including obstipation, cystitis and endometritis, are discussed.
