Immunohistochemistry of bone-marrow biopsy

Abstract

In a percentage of cases, conventional morphologic evaluation of bone-marrow needle biopsy (BMNB) in insufficient to achieve a firm diagnosis. Under these circumstances, immunohistochemistry plays a basic role, providing an easy and objective key for the interpretation of the pattern observed in most instances. Herein, the authors focus on the technical procedures, which allow extensive application of immunohistochemistry to the study of BMNB, as well as on the panels of antibodies needed for the identification of the most relevant conditions.
