The salivary glands are unique in the diversity and complexity of their pathologies. Because fine needle aspiration cytology and frozen section are associated with major diagnostic difficulties, the authors analyzed the use of core needle biopsy (CNB) for the histologic assessment of salivary gland lesions. A systematic observational clinicopathologic quality assessment study was performed over 81 months including 161 CNB procedures in 76 patients with salivary gland pathologies. Adequate samples containing the target tissue were obtained in 73 patients. These samples revealed malignant disease in 45 (62%) patients, benign disease in 26 (36%) patients, and were inconclusive in 2 (3%) patients. Follow-up uncovered no false-positive or false-negative results. On the basis of secondary histologic and clinical follow-up, the statistical parameters were calculated as follows: sensitivity 94%; specificity 100%; accuracy 96%; positive predictive value 100%; negative predictive value 90%. The advantages and potential limitations of CNB in patients with salivary gland masses are discussed. CNB is a reliable biopsy technique for the assessment of salivary gland pathologies, although limitations remain for the subclassification of some neoplastic lesions. The authors recommend CNB as the biopsy technique of choice for a selection of indications.
