#Morphology still matters! Our new review in @Human_Pathology looks at the morphologic clues that can point toward specific genetic subtypes of #AML

From the classic findings of APL and core binding factor leukemias to the more subtle patterns associated with NPM1, CEBPA, MECOM, TP53 and others, the microscope still has a great deal to tell us.

Really enjoyed working on this with Jessica Anderson-Calleja and Vida Ehyaee. Thanks for the invitation to contribute @sanamloghavi and Dr. Jeff Medeiros #hemepath

This phenomenon is called «garland pattern» — obliteration of the ductal lumen observed in the last stage of ectasia. After obliteration, the lumen recanalizes at the periphery.

For Path trainees, “No field of medicine demands daily reading more than pathology; gaps in knowledge are quickly exposed and revealed.”
