The objective was to conduct a retrospective study of cytological examinations in the period of six years and then calculate accuracy, sensitivity and specificity of cytology examination for neoplasms in cutaneous and subcutaneous samples collected by PAF (fine needle punction) in dogs, using histology as golden pattern. The canine species was the most common in 92.2% (736/798). The PAF was the most used technique in 84.0% (814/968). The most frequent samples were from the Cutaneous System in 36.1% (344/951). There was 67.0% (36/53) agreement between the exams. The sensitivity of cytology in the diagnosis of neoplasms was 77% (moderate) and specificity of 12.5% (low), and the PPV 83% and NPV 9.0%. Cytology is the most commonly test used in cutaneous and subcutaneous lesions in dogs and the PAF is the most used technique. The examination is recommended as a screening method because of its high sensitivity.
