Now that we know the answer is MDS-biTP53 let's see how we got to the answer...
I'll start from the beginning.. what exactly is this image that I showed you?
It's a whole genome view of using @bionano 's #OGM of a BM aspirate.. giving U a bird's-eye view of the chromosomes 1/
How do we interpret this? Easy!
normal cells have 2 copies of somatic chromosomes (1-22) one X & one Y if male, and 2 X if female.. (with some normal exceptions: i.e. men tend to lose their Y as they age... we think it's normal🤷♀️ or at least a very common somatic mosaicism) 2/

Best way to recognize pathological/neoplastic immunophenotypic changes is having a good grip on immunophynotypic variations in reactive/regenerative conditions… summarizing #FlowICCS22 plenary session 3 here👇🏻 🧵1/ #hemepath
Normal granulocytic maturation patterns…. Plots follow maturation from promyelocyte (*) to neutrophils #flowiccs22#hemepath 2/

@AaronGoodman33 Typical cytomorphology is characterized by “blasts” with hand mirror (red arrow, cytoplasm to the side) or pearl necklace (green arrow, small cytoplasmic vacuoles around nucleus) appearance #bpdcn#hemepath#RareDisease#WHOHEME 1/ @AaronGoodman33 Skin and lymph node are most common extramedullary sites of involvement. Skin infiltrate is usually dermal with an appreciable “grenz zone” (uninvolved band b/w dermis and epidermis).. Lymph node typically has diffuse or paracortical involvement #hemepath#WHOHEME#BPDCN

One of the difficult aspects of #hemepath training is time management in a high-paced/demanding environment & the ability to multitask effectively while learning a difficult discipline. Every yr I offer our fellows helpful tips I’ve learned so far 🧵👇🏻More tips welcome,pls add 1/
Get rid of paper…
Don’t do anything twice
Take ownership of your cases… they are just as much yours as they are your faculty’s

Happy to share our latest paper w/ @SibaElHussein as lead author, out today in @BMTjournal ⚡️Acquired WT1 mutations contribute to relapse of NPM1mut AML following allogeneic hematopoietic stem cell transplant rdcu.be/cEuxv#hemepath#leukemia#hemepathMDA
WT1 mutations are present in ~7% of de novo AML, are typically Lof mutation involving exons 7-9 of the gene. They frequently (~15%) co-occur w/ NPM1mut & have detrimental impact in this setting, shown by @AkEisfeld and colleagues in bit.ly/3eWQtXw@LeukemiaJnl
