Resumen

WHITTLE P, Carolina et al. Fine needle aspiration in salivary gland tumors. Rev. chil. radiol. [online]. 2014, vol.20, n.3, pp.91-95. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082014000300003.

Imaging studies allow the diagnosis and classification of a salivary gland (SG) tumor. Fine needle aspiration (FNA) is a diagnostic tool. Ultrasound (US) allows the visualization of the tumor and guidance of the needle in FNA. Objectives: To describe the FNA technique. A retrospective review of the results of ultrasound guided FNA in a SG tumor. 39 patients referred for FNA in 5 years, were analyzed. Results: 31 parotid and 8 submaxillary lesions. 87% presented as hypoechoic nodule and 69% with posterior acoustic enhancement. Cyto-histological results of 36 FNA performed: 29 benign lesions, 6 malignant lesions, one failed puncture. There were no complications. 21 operated patients. Histological concordance was 85%. There were no false positives for cancer. In conclusion, FNA using ultrasound is a diagnostic tool in GS tumors.
