biopsy

(bīäp`sē), examination of cells or tissues removed from a living organism. Excised material may be studied in order to diagnose disease or to confirm findings of normality. Preparatory techniques depend on the nature of the tissue and the kind of study intended. Incisions may be made and total or partial lesions removed in the form of wedges or cylindrical pieces, or scrapings of the surface membranes of internal organs may be collected. Needlelike instruments may be used to pierce the tissues and remove soft inner material. Once the tissue specimen has been obtained it is fixed, i.e., membrane proteins and enzymes are stabilized and chemical and histologic analyses are carried out by pathologists. Tumors are routinely biopsied in order to determine whether they are malignant. Fine needle aspiration is a technique more readily used for certain tumors or lesions because it is less expensive and damaging than traditional surgical biopsy.

Because all forms of non-Hodgkin's lymphoma, including newly recognized entities such as monocytoid B-cell lymphoma and anaplastic large cell lymphoma (Ki-1 positive) can have circulating lymphoma cells, it is imperative to correlate appearances of circulating lymphoma cells with those of the lymph node biopsy, bone marrow biopsy, and with all available immunophenotypic and clinical data.

In our patient, the presence of MYD88 at bone marrow biopsy on relapse in 2016 along with increased monoclonal free kappa light chains contributes evidence (albeit not exclusive) favoring a diagnosis of WM over LPL since MYD88 is now known to be present in 95% of WM cases [8,9] but was reported to be absent in 9 cases of LPL [6].
