Objective. Histopathology of parotid gland tumors is extremely varied and complex due to heterogeneous cellular composition. Preoperative diagnostic tools include fine needle aspiration cytology, the role of which remains controversial. The aim of this paper is to evaluate the usefulness and accuracy of fine needle aspiration cytology (FNAC) in the diagnosis of parotid gland tumors. Methods. We retrospectively reviewed charts of 129 patients who underwent parotidectomy for parotid lesions at Aga Khan University Hospital from 2002 to 2010. We compared the results of preoperative FNAC with final histopathological diagnosis. Results. Concordance with histological results was observed in 86%, specificity was 98%, sensitivity was 84%, and diagnostic accuracy was 94%. Conclusion. Our results demonstrate that preoperative cytology in parotid lesions is fairly accurate and useful in diagnosing benign from malignant and in planning appropriate approach for treatment.
目的。由于细胞组成的异质性，腮腺肿瘤的组织病理学极其多样且复杂。术前诊断工具包括细针穿刺细胞学检查，其作用仍存在争议。本文旨在评估细针穿刺细胞学检查（FNAC）在腮腺肿瘤诊断中的实用性和准确性。方法。我们回顾性分析了2002年至2010年在阿迦汗大学医院因腮腺病变接受腮腺切除术的129例患者的病历。我们将术前FNAC的结果与最终组织病理学诊断进行了比较。结果。与组织学结果的一致性为86%，特异性为98%，敏感性为84%，诊断准确性为94%。结论。我们的结果表明，腮腺病变的术前细胞学检查在诊断良恶性以及规划适当的治疗方法方面相当准确且有用。
