Bir kobayda (cavia porcellus) meme tümörü sonrası uterus leiomyosarkomu ve bilateral over kistleri

Beş yaşında, kısırlaştırılmamış, dişi kobay sağ meme lobunda bir kitle şikayeti ile kliniğimize getirildi. Ultrasonografik muayeneye göre kitle; kapsüllü, 8,1 cm çapında, polikistik yapıda, miks ekojenite ve miks vaskülarizasyona sahipti. Hastaya mastektomi uygulandı. Kitlenin histopatolojisi sonucunda solid karsinom teşhisi konuldu (Grade-III). Mastektomiden ortalama 2,5 ay sonra kobayda karın şişliği meydana geldi. Laparotomi sonrasında her iki overde de kist ve korpus uteri üzerinde leiomyosarkom içeren kitle saptandı. Sonuç olarak, meme tümörü öyküsü olan gine piglerde metastas ihtimaline karşı genital organ patolojileri klinik açıdan mümkün olan en kısa süre içerisinde değerlendirilmelidir.

Uterine Leiomyosarcoma and Bilateral Ovarian Cysts Subsequent to Mammary Tumor in a Guinea Pig (cavia porcellus)

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.
