Keywords:Ductal carcinoma, mammary gland, German Shepherd, dog
AbstractA German Shepherd bitch of about 2.5 years old showed swollen ulcerated L-5 mammary gland. The affected L-5 gland and adjacent lymphnode were excised and processed for histopathological study with routine Hematoxylin and Eosin staining method. The ductular epithelial cells showed polymorphism and adenoid pattern growth of cells with hyperchromatric nuclei. Metastasis was not evident in the excised lymphnode. The neoplastic epithelial cells infiltrated the surround tissue. On the basis of histopathological finding this case was diagnosed as infiltrating ductal carcinoma.
