@HalletJulie @EndoCancer @IHC_guy @OncoThor @WinshipAtEmory @NANETS1 @ENETS_ORG @ChandrikhaC @SethConcorsMD @UTSW_Surgery I’m honored 😊 Thank you so much. Thanks to @IHC_guy for brainstorming this with me and making sure I included all the key studies- and of course for the beautiful images from his transformation cases.

I have heard of synthetic lethality & collateral lethality but today at #AACRDrugDev26 (a.k.a. @AACR D3 meeting) Bill Sellers spoke about an interesting concept called “hyperactivation lethality”. cell.com/trends/cancer/… D3 is a great meeting that will only grow over time!

#AAPath26 Boston reminded me why I love academic pathology! Heading back to Ann Arbor energized by conversations with friends, inspired by the next generation of trainees + educators, and convinced that our greatest advances will come from investing in people as much as technology! The past few days I had the privilege to contribute to a timely discussion on shaping pathology education for the Millennial, Gen Z, and future physician workforce, presenting our work (with the super duper @cullen_lilley) on an AI-driven pathology case tutor, coxxntinuing to serve on the Society of '67 Board, the Academy of Distinguished Pathology Educators, and the Editorial Board of @AcadPathol! I was especially proud to see @UMichPath so well represented across the meeting (Chairs, UMEDs, PRODs!) #GoBlue MISSING so many pictures with lots of people but shout out to all! #AAPath2026 #Pathology #MedicalEducation #PathEd #AcademicPathology #Leadership @apcprods @Klowsanford1027 @JMGardnerMD

As a CUP-ologist, I am always happy to show CUPs some love at cancer conferences. Here, @hfuentesbayne showed why he has become a recognized go-to person for all things CUP and why he is the Chair of the CUP Group at Mayo Clinic in Rochester. An excellent review on the management of patients with CUPs. Need a CUP speaker for a conference or a grand round...? I have his email and I am willing to share it... 😉

New article out now #AIMMhighlights ▶️CD30 and Cyclin D1: 100% positive and OCT2: 90% positive in RDD ▶️ Helpful IHC panel for distinguishing RDD from LCH, IMT & IgG4-RD

Happy to share our invited review on "Grade progression and high-grade transformation in Neuroendocrine Neoplasms" just out in @EndoCancer. 🔗 shorturl.at/UpxlF Forever grateful to @IHC_guy for his mentorship on this and several other projects (crazy that I even know you and get to work with you). We hope that this will be a helpful guide for colleagues while dealing with this clinical challenge that I find to be incredibly hard to navigate. Thank you @NANETS1 for the nomination and co-authors @ChandrikhaC @PoHienEar @RaulSGonzalezMD @SethConcorsMD for your contribution to this work.

Saving one of the best for last! Don't miss the final ISIMm webinar of the season. Share broadly with colleagues, trainees, and anyone interested in GI pathology and precision oncology. @ISIMMweb @IHC_guy @AimmJournal
