Two Diagnoses in One Bone Marrow with Megan Nakashima, MD

Analysis of a bone marrow requires both careful morphologic examination as well as appropriate ancillary studies. Dr. Nakashima, Staff Hematopathologist at Cleveland Clinic, discusses a complicated bone marrow case involving a patient with thrombocytopenia, monocytosis, and diarrhea. After requiring the incorporation of molecular and immunophenotypic information, two diagnoses are reached. In addition to this case, Dr. Nakashima reviews relevant changes in the WHO 2016 classification of myeloid and associated neoplasms.
