Hernia abdominalis with prolapsed urinary bladder and uterine adenocarcinoma in a rabbit after ovaryectomy

A 6-year-old female, pet rabbit after ovaryectomy was presented due to dyspnea and a swelling in the anogenital region. After detailed anamnesis, clinical investigation, further diagnostics (radiography and sonography), and blood analysis an abdominal herniation with prolapsed urinary bladder and uterus was diagnosed. During laparotomy a tumor of the uterus was found and therefore hysterectomy was performed. Histopathologic examination revealed an uterine adenocarcinoma. The urinary bladder was relocated to the abdominal cavity and the hernia orifice was closed. The rabbit recovered well and was released the day after. The detection of an uterine adenocarcinoma in a rabbit after ovaryectomy is the first report of that kind in the German literature according to the authors' knowledge.
