Abstract

Canine mammary tumor is the most common neoplasm with worldwide distribution. In present study a total of 30 spontaneous canine mammary tumors were evaluated based on cytology, histopathology and immunohistochemistry. Histological classification revealed 66% malignancy. Correlation of cytological and histological diagnosis was found to be 70%. Immunohistochemical staining with estrogen receptor (ER) and progesterone receptor (PR)showed decreased expression with progression of malignancy.
