Lymph Node Fine-Needle Aspiration Cytology: Technique, Rapid On-Site Evaluation, and Ultrasound Guidance

LN-FNAC is adaptable to a broad range of clinical scenarios, including infectious and inflammatory conditions as well as metastatic disease and lymphoproliferative disorders. By integrating US evaluation, high-precision image-guided LN-FNAC sampling, ROSE, and the targeted use of ancillary techniques, LN-FNAC moves beyond a simple screening approach and represents a cornerstone of modern minimally invasive diagnostics.
