Cytologic examination is useful in the diagnosis of NPC. The actual yield in exfoliative cytologic diagnosis can be improved by a better designed applicator. Metastatic NPC in lymph node FNA shows certain features that are diagnostic. Detection of EBNA can be done with smears from fine-needle aspirates and may help to exclude NPC from the diagnosis if they are negative.
