Core Needle Biopsies in Patients With Lymphoproliferative Malignancies: An Observational Single‐Center Cohort Study

open access: yesEuropean Journal of Haematology, Volume 116, Issue 1, Page 85-92, January 2026.
ABSTRACT In the diagnostic evaluation of suspected lymphoma, both core needle biopsy (CNB) and surgical excisional biopsy (SEB) are routinely employed for tissue sampling. While SEB remains the gold standard, CNB is a less invasive and more cost‐effective alternative. However, concerns persist regarding its diagnostic yield.
