Introduction: Fine needle aspiration cytology (FNAC) of salivary gland lesion is being increasingly used. Major salivary glands and some minor salivary glands are optimal targets for fine-needle aspiration (FNA). In some instances the final histology of these lesions differs from the FNA result.
Fine needle aspiration cytology (FNAC) is being increasingly used in the diagnosis of salivary gland lesions. Major salivary glands and some minor salivary glands are easily accessible; therefore they are optimal targets for Fine Needle Aspiration (FNA). Different studies reveal high sensitivity and specificity of FNA with few pitfalls1-3. It has some edge over an incisional biopsy and frozen section. FNAC is a simple, quick, useful and reliable procedure. Wide sampling of the lump is possible. This procedure takes only 5-10 minutes and result could be available after 15-20 minutes. In majority of cases FNA is helpful in differentiating between benign and malignant lesions. However due to diverse morphological patterns and overlapping features between benign and malignant lesions, distinction between two is not very easy in every case. Thus at times it becomes very challenging and difficult to give precise diagnoses. The aim of the present study is to discuss pitfalls and problems in salivary gland lesions and try to find out possible solutions.
