Algorithmic Approach to Salivary Gland FNA: An Overview
This book uses a simplified and practical algorithmic approach to evaluate and diagnose a wide range of non-neoplastic, benign, and malignant entities encountered in salivary gland cytopathology (Fig. 3.1). After verifying that the FNA sample is indeed satisfactory for evaluation, the cytotechnologist or pathologist focuses upon the general types of cells, matrix, and inflammatory components that are present to fit the aspirate into 1 of 3 major arms of the algorithm based upon the overall cytomorphologic pattern. This will result in a focused differential diagnosis for the lesion. Detailed application of this algorithmic approach and distinction between different entities within the differential diagnoses are discussed and illustrated within specific subsequent chapters of this book. Because some salivary gland tumors can exhibit more than one general cytomorphologic pattern (e.g., mucoepidermoid carcinoma can be cystic, high-grade, or oncocytic), several entities will be presented and discussed in the differential diagnosis of more than one arm of the algorithm.
