The cytopathology exam has been utilized to diagnose mammary disorders in female dogs. The success of cytopathology results depends on, among other factors, the diagnostic accuracy of the exam. The present study aimed to compare the cytopathological and histopathological findings from mammary disorder cases in female dogs and evaluate the lesion cytopathology exam accuracy. The concordance degree was evaluated between the cytopathology and histopathology exams of 67 female dogs, carriers of palpable breast lumps, cared for at the university hospital from which the following indicators were calculated: sensitivity, specificity, positive predictive value, negative predictive value, false positives, false negatives, and exam accuracy. The sensitivity was 95.23%, the specificity 75%, positive predictive value 98.36%, negative predictive value 60%, and accuracy 94.02%. There were 2 false negatives and 1 false positive. In conclusion the cytopathology exam can be amply utilized as a means of diagnosis with high accuracy and sensitivity in the first examination of female dogs with mammary tumors.
