title: Estrogen receptors in canine mammary gland tumours.
abstract: The aim of the present study was to establish the relationship between estrogen receptor expression in neoplastic parenchymal cells and the type of canine mammary gland tumour. The research material included mammary gland tumours obtained from 66 dogs. Paraffin sections were stained with hematoxylin-eosin and immunohistochemically with monoclonal antibodies and LSAB/Peroxidase/Universal Kit. The estrogen receptor expression was observed in nuclei of neoplastic cells in about 59% of the cases and in the cytoplasm in about 89% of the cases. In about 20% of the cases the expression in the nuclei and in the cytoplasm was extremely weak. No correlation was found between the expression of estrogen receptors and the value of mitotic indexes in the neoplasms investigated.
