Abstract The present study was aimed to evaluate the correlation between cytological and histopathological techniques in diagnosis of canine skin tumours. A total of 66 cytological and histopathologic specimens were collected from dogs suspected for the tumorous growths. Cytologically, 55/66 cases were diagnosed as neoplasms, while 52/66 cases were confirmed as neoplastic growths by histopathology. As histology is gold standard for tumour diagnosis, cytological diagnosis showed 94.54% true positive and 5.46% false positives cases. True positive cases included 38 epithelial tumours, 3 mesenchymal tumours and 11 round cell tumours. Nine cases diagnosed non-neoplastic in cytology were confirmed by histopathology as true negative, however, two cases were found to be false negative. Sensitivity and specificity of cytological diagnosis was found to be 96.29% and 75%, respectively, which indicated that cytological method can provide an early insight to diagnosis of skin tumours in canine.
