[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.
