Fine-needle aspiration effects on benign lymph node histology.
American Journal of Clinical Pathology
|August 1, 1984
Summary
Fine-needle aspiration (FNA) before biopsy does not impact lymph node histology. Our study found that even when needle tracts were present, they did not interfere with accurate lymph-adenopathy evaluation.
Area of Science:
- Pathology
- Surgical Pathology
- Diagnostic Cytology
Background:
- Fine-needle aspiration (FNA) is a common diagnostic procedure.
- Concerns exist regarding potential interference of FNA with subsequent biopsy evaluation.
- Histological assessment of lymph nodes is crucial for diagnosing lymphadenopathy.
Purpose of the Study:
- To evaluate the impact of prior fine-needle aspiration (FNA) on the histological examination of lymph nodes.
- To determine if FNA affects the accuracy of lymph-adenopathy diagnosis.
Main Methods:
- Histological examination of 28 lymph nodes with benign hyperplasia.
- Assessment for evidence of prior fine-needle aspiration (FNA).
- Quantification of needle tract presence and size.
Main Results:
- Only 43% of lymph nodes showed evidence of prior aspiration.
- Needle tracts occupied less than 5% of any section in most cases.
- Prior FNA did not interfere with the histological evaluation in any of the 28 lymph nodes.
Conclusions:
- Fine-needle aspiration (FNA) does not interfere with subsequent histological evaluation of lymph nodes.
- FNA is a safe pre-biopsy procedure for lymphadenopathy assessment.
- Histological interpretation of lymph nodes remains reliable after FNA.
