Liver metastases in mammary carcinoma in female dogs: case study.

At female dogs, the malign tumors have metastases potential, both on lymphatic way at the regional lymphatic nodules, as well as on sanguine way, on the lungs or in distant places of the body, including liver, spleen, heart and boned system. This case study presents a half-blood female dog, 11 years old, with mammary tumors at the level of the right mammary chain (M5) and partial mastectomy (M3, M4, M5), on the left mammary chain. The clinical examination also underlined ascites, anorexia, diarrhea and severe dyspnoea. The female was undertaking several complementary examinations: ultrasound, radiology, necropsy and histopathology. The ultrasound examination revealed the presence of liver hypoand hyperechogenicity. The radiological examination revealed the presence of a large sized radio-opaque area (1.5-2 cm) on the right pulmonary diaphragmatic lobe and on the left cardiac lobe an area of smaller sizes (0.5 cm). From the necropsy perspective, besides the pulmonary and hepatic lesions revealed following the complementary imagistic examinations, it was revealed the presence of both pancreatic and renal metastases. The histopathological examination from the mammary lesion revealed the presence of a malignant epithelial tumor, the diagnosis being of complex type mammary carcinoma. The histopathological examination of the liver confirms the fact that the liver metastases have the same origin as the one in the mammary chain.
