Purpose:
It is critical to obtain sufficient tissue, both in quality and quantity, in biopsy applications for histopathological review. Our aim was to compare fine-needle aspiration cytology (FNAC) and core needle biopsy (CNB) techniques in terms of their diagnostic performance in lymph node biopsies. This was a clinical compilation, and histopathological results from biopsies were also evaluated.
Methods:
A total of 242 patients and 246 lymph nodes were prospectively evaluated. All histopathologic specimens were obtained through ultrasonography-guided biopsies performed at our institute between April 2015 and October 2017. Histopathological results were grouped according to diagnostic performance, and the mean performance scores of the two methods were compared.
Results:
For FNAC, the mean diagnostic score was calculated to be 1.63, whereas for CNB, the mean diagnostic score was calculated to be 1.89. The difference between diagnostic scores of the two techniques was statistically significant (p < 0.01).
Conclusion:
We recommend that interventional radiologists perform vacuum-assisted biopsies if there are no financial hindrances or evidence of psychological issues in patients. We recommend this not only for lymph nodes of malignant appearance but also for those that appear benign.

Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
