Diagnostic Considerations in the Evaluation of Large B-Cells on Lymph Node Cytology Specimens

Abstract

Fine needle aspiration (FNA) has become increasingly popular in the evaluation of lymph nodes for lymphoproliferative disorders, but there are limitations to accurate subclassification of lymphoma using morphology alone. This case aims to expand diagnostic considerations of large B-cell populations identified on FNA material. We also address the significance of Epstein-Barr virus (EBV) DNA in the workup of patients with suspected lymphoma by FNA.
