All pathology subspecialties are more frequently receiving small needle core biopsies for the diagnosis of new lesions. While this results in potential diagnostic pitfalls, the tools available for hematopathology, including extensive panels of immunostains, PRC-based clonality assessment, and flow cytometry often allow accurate diagnoses even with very small specimens. This review presents a brief approach to such biopsies, using morphologic cues as well as ancillary studies, which provides an experience-based framework for approaching these cases and coming to a clear diagnosis while avoiding diagnostic errors. The approach is divided into three parts based on H & E cell morphology.
