Complete clinical information on the patient and aspirated lesion, proper aspiration technique, and an adequate sample of well-fixed, correctly stained cellular material for microscopic evaluation are crucial to maintaining a high level of accuracy in fine-needle aspiration biopsy (FNAB).<BR>In North America, FNAB of superficial organs is done by trained pathologists to assess the adequacy of the specimen on the spot, triage the lesion based on air-dried Diff-Quick stained smears, and provide the clinician with a preliminary diagnosis.<BR>To obtain sufficient material by FNAB, the cutting effect of the advancing sharp oblique needle tip produced by the needle being moved back and forth within the lesion plays a major role compared to negative pressure created in the syringe. Also important is moving the needle back and forth in various directions within the lesion to minimize sampling error.<BR>There are many diverse organ-specific approaches to disease, and pathologists must have sufficient knowledge and be given a more important role in FNAB practice.
