March 2023—Updated classifications for hematologic neoplasms are here. Let the complications continue. As with other specialties, hematopathology has been absorbing advances gleaned from molecular and genetic data. In some cases, this can tilt diagnosis away from primarily immunophenotypic approaches. It might lead to splits in what was formerly a single entity. On occasion, it might suggest further testing options that could be of value to patients now, or possibly at a date down the road. Or it might just leave pathologists and their clinical colleagues peering at a lack of data, knowing they have to make decisions nonetheless. Two groups—the World Health Organization and the International Consensus Classification—have put forth classifications to help physicians sort through the complexities. The WHO published a beta version of the fifth edition of its Classification of Haematolymphoid Tumours in July 2022.

October 2020—B-ALL with aberrant expression of myeloid markers should be investigated further for specific gene abnormalities, including ZNF384 rearrangements, and microarray analysis may play an important role.

March 2016—At the annual meeting of the Association for Molecular Pathology in November 2015, one plenary session was called “Exciting Times for Translational Research in Molecular Hematology.” In accord with the title, Margaret Goodell, PhD, gave an exciting talk about how hematopoietic stem cells are regulated in mice. While Dr. Goodell’s basic research was impressive, what was most remarkable was how it meshed with and anticipated research in human hematopoietic malignancies from other laboratories.
