Fine-needle aspiration of 154 parotid masses with histologic correlation

Abstract

FNA of parotid masses at a major referral cancer center has a sensitivity of 82%, a specificity of 86%, and an overall diagnostic accuracy of 84%. FNA plays an important role in the preoperative and postoperative assessment of parotid masses by aiding in the evaluation of tumors in poor surgical candidates and unresectable tumors, and by identifying metastases from other sites, reticuloendothelial tumors, and nonneoplastic inflammatory conditions.
