Abstract :A 5-year-old, intact female guinea pig was brought to our clinic with a complaint of a large mass in the right mammary lobe. According to ultrasonographic examination, the mass was encapsulated, had a diameter of 8.1 cm, exhibited a polycystic structure, mixed echogenicity, and mixed vascularization. The patient underwent mastectomy. Histopathological analysis of the mass revealed a diagnosis of solid carcinoma (Grade-III). Approximately 2.5 months after mastectomy, the guinea pig developed abdominal swelling. Upon laparotomy, cysts were identified in both ovaries, and a mass containing leiomyosarcoma on the corpus uteri was detected. In conclusion, guinea pigs with a history of mammary tumors should be evaluated for genital organ pathologies as a precaution against the possibility of metastasis at the earliest opportunity.
