Lymph node core needle biopsy for the diagnosis of lymphoproliferative disorders: a word of caution

We read with interest the study by Cohen and colleagues addressing the role of lymph node core biopsy (LNCB) for the diagnosis of lymphoproliferative disorders (LPDs) (1). Although we agree that LNCB provides diagnostic clues in most instances, we think that it should not be adopted routinely. We believe, instead, that incisional/excisional biopsies should be performed in all suitable cases. This view is supported by everyday clinical practice and literature data
