BACKGROUND: Fine-needle aspiration biopsy (FNAB) is an important tool for the cytologic assessment of patients with lymphadenopathy. The nonaspiration method (without the use of a syringe or a handle), or fine-needle capillary biopsy (FNCB), is becoming popular for its ease of learning and use. The authors compared the two techniques of fine-needle biopsy (with and without aspiration) for identifying the cause of superficial lymphadenopathy.
METHODS: Over a 2-year period 50 cytologic examinations were conducted in patients with superficial lymphadenopathy. Both procedures were performed at the same site; the order in which they were performed was determined randomly. Slides were fixed in a similar manner and examined by a cytotechnologist and pathologists blind to the procedure. Scores were tabulated and compared and diagnosis was confirmed by histologic examination.
RESULTS: The best and the average score for the yield of cellular material was higher with FNCB (P < 0.004). Cell preservation also was superior with FNCB (P = 0.00066). However, the failure rate was lower with FNAB (P = 0.7662).
CONCLUSIONS: FNCB of superficial lymph nodes yields adequate cellular material of superior quality, which may be advantageous in certain situations. However, the diagnostic yield does not appear to be significantly increased using this technique.
