| Abstract: | Two female chinchillas were presented with reduced appetite and production of small fecal pellets. Physical examination of both chinchillas revealed a reduced vaginal membrane, bloody vaginal discharge, and a palpable mass in the caudal abdomen. Radiographic images revealed soft tissue masses in the caudal abdomen of both animals. In addition, the first case was examined by ultrasound, which identified 2 cystic masses, each originating from 1 of the uteri. Both chinchillas were euthanized due to progressive clinical deterioration with both animals undergoing postmortem examinations. Grossly the uterine masses were confirmed, in the first case adhering to the jejunum and mesojejunum and in the second case leading to compression of the rectum in the pelvic cavity. Histopathological examination and immunohistochemical staining of the masses were consistent with presence of uterine leiomyoma and fibroma in the first case and a uterine hemangioma in the second case. The bloody vaginal discharge was assumed to be caused by the fibroma with multifocal acute hemorrhages and rupture of the hemangioma, respectively. The presented cases intend to increase the knowledge base of chinchilla oncology. |
