Abstract
An 11-year-old female goat had invasive and metastatic endometrial adenocarcinoma in the
uterus. There was a notable proliferation of endometrial epithelial cells in a tubular
growth pattern, with a desmoplastic response. The endometrial epithelial tumor cells
metastasized to the kidney, liver and lung. In contrast to the primary and metastatic
tumor cells, pleomorphic tumor cells with a choriocarcinoma-like growth pattern
infiltrated the mesometrium. Cell proliferation activity was high in both types of tumor
cells. Both types of tumor cells expressed cytokeratins AE1/AE3, 7 and CAM5.2;
choriocarcinomatous cells also had positive immunoreactions to human chorionic
gonadotropin, human placental alkaline phosphatase and α-inhibin. The present case was
diagnosed as endometrial adenocarcinoma with choriocarcinomatous differentiation.

Abstract
Reproductive pathology of domestic guinea pigs is underreported to date. To provide a comprehensive review of uterine disease in guinea pigs, we performed a retrospective study of the pathology archives of the University of Tennessee, College of Veterinary Medicine. By histology, 13 of 37 uterine lesions in 23 animals were neoplastic; the other 24 nonneoplastic lesions included cystic endometrial hyperplasia (16 of 24), endometrial hemorrhage (3 of 24), pyometra (2 of 24), polyp (2 of 24), and mucometra (1 of 24). The most common guinea pig uterine neoplasms were uterine leiomyomas (6 of 13), followed by adenomas (3 of 13) and leiomyosarcomas (1 of 13). Other neoplasms included anaplastic tumors of unknown origin (2 of 13) and choriocarcinoma (1 of 13). Both anaplastic tumors and the choriocarcinoma were positive for vimentin. The choriocarcinoma was positive for HSD83B1, indicating a trophoblastic origin and its final diagnosis. All were negative for cytokeratin and smooth muscle. In multiple animals, more than 1 tumor or lesion was reported. Estrogen receptor and progesterone receptor expression was nearly 100% in uterine neoplasms. Nearly all animals for which data were available had cystic rete ovarii (18 of 19); the animal with no cystic rete ovarii had paraovarian cysts. In our study, female pet guinea pigs had a tendency to develop cystic endometrial hyperplasia and uterine neoplasia. Factors for the development of these lesions could be cystic rete ovarii, hormone dysregulation, and/or age. Other factors could contribute to the development of uterine lesions. As in other species, early ovariohysterectomy could decrease the prevalence of uterine lesions.

Abstract
Resumo: Neoplasmas em suínos são raros. Esse trabalho descreve os neoplasmas encontrados em suínos na rotina diagnóstica de um laboratório de patologia veterinária localizado na Região Central do Rio Grande do Sul. Durante um período de 49 anos, 2.266 casos de várias afecções em suínos foram encontrados, dos quais 37 (1,6%) eram neoplasmas. Em ordem decrescente de frequência, os seguintes neoplasmas foram encontrados: Linfoma (11/37), nefroblastoma (11/37), melanoma (8/37) e papiloma (2/37). Adicionalmente, um caso de cada um dos seguintes tumores foi observado: Adenoma hepatocelular, carcinoma hepatocelular, colangiocarcinoma, histiocitoma fibroso maligno e sarcoma granulocítico. O aspecto macroscópico e histológico desses tumores é descrito e a sua epidemiologia é comparada com os dados disponíveis na literatura para neoplasia suína.
