Breast adenocarcinoma in Oryctolagus cuniculus: case report

Abstract

Neoplastic processes in exotic animals still have few reports in the literature due to their scarce investigation and diagnosis. Rabbits have been more adopted as companion animals and, thanks to the advances in veterinary medicine, they obtained an increasing life expectancy, accompanied by pathological processes correlated with age, mainly those of a neoplastic nature. Mammary carcinomas in lagomorphus usually have a direct correlation with the reproductive system in non-castrated and elderly patients. The present work reports a case of a 5-year-old female rabbit, not castrated, who was diagnosed with cystic to papillary mammary adenocarcinoma, with the invasion of the deep margin through cytological analysis and diagnostic confirmation in histopathological analysis.
