Abstract / Zusammenfassung

Pathological changes aff ecting the female reproductive tract in guinea pigs have been described previously in the literature. However, knowledge about the clinical fi ndings and management of uterine and vaginal proliferative diseases has been sparse to date. In dogs, a common clinical presentation of various types of uterine and vaginal abnormalities is a tumor-like mass protruding from the vaginal orifi ce. In the present study, we investigated the frequency and underlying causes of masses protruding from the vaginal orifi ce as the reason for presentation in guinea pigs. A retrospective analysis of pathological and associated clinical records of a total of 723 intact female guinea pigs identifi ed masses protruding from the vaginal orifi ce in 12 animals (1.7%). Of these, six originated from the vagina – four vaginal leiomyomas and two non-neoplastic vaginal polyps– and six from the uterus – two cervical gland neoplasms, two decidual cell proliferations, and two uterine prolapses. Additionally, four cases of decidual cell proliferations being discharged from the uterus and subsequently found in the animal’s cage were identifi ed. All six vaginal masses were successfully removed by simple ligation through the vaginal opening. The resection of three uterine masses by simple ligation resulted in an incomplete surgical removal. In conclusion, diff erential diagnoses for vulvar masses in guinea pigs should include vaginal or uterine neoplastic or non-neoplastic proliferative disorders. Knowledge of the anatomical origin and type of disease is essential for the therapeutic management. Most notab-ly, although decidual cell proliferations are thought to regress spontaneously, they may also be associated with uterine neoplasia and so necessitate a thorough clinical examination of the uterus.
