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

In this case, the core biopsy disclosed a diffuse proliferation of CD20-positive mature B cells, leading to a putative diagnosis of indolent non-Hodgkin B-cell lymphoma. Randomized comparison of power Doppler ultrasonography-guided core-needle biopsy with open surgical biopsy for the characterization of lymphadenopathies in patients with suspected lymphoma. Excisional biopsy of the same lymph node disclosed scattered Hodgkin/Reed-Sternberg (HRS) cells (insert), which were not evident on first biopsy. [Extracted from the article]
