Lynn D. Cornell, M.D.

The Banff 2024 meeting report is official! Link to the article (free access) is below- now get ready for the next Banff meeting, October 5-9, 2026, in beautiful Banff, Alberta, Canada!! authors.elsevier.com/sd/article/S16… @Renalpathsoc #renalpath

@sam_albadri @Renalpathsoc @MayoClinicPath @MayoClinicNeph Love this! Well said Sam.

Even in the presence of immune complex deposits within the glomerular basement membrane, we are reminded that beyond the science, there is always compassion guiding our diagnosis. Pathology teaches us that even in complexity and injury, there is structure, meaning, and purpose, and at the center of it all, a heart committed to healing.

@sam_albadri @MayoClinicPath @MayoClinicNeph @Renalpathsoc Congratulations!!! 🥳

Congratulations to Dr. Belinda Galeano on winning Best Abstract at the 6th International Renal Pathology Conference (#IRPC2026) in Antigua, Guatemala! 🏆🎉 Her outstanding work on single-cell spatial transcriptomics and macrophage biology in antibody-mediated rejection continues to advance the field of transplant pathology. So proud of our former Renal Pathology fellow! 👏🧬 #RenalPathology #KidneyTransplant #TransplantImmunology

@JZRenalPath @sam_albadri @Renalpathsoc The Banff scores are diagnosis-agnostic. I think the A/C indices (at least initially) should just apply to rejection… in the Banff post meeting survey, only 66% said that we should consider reporting these indices on all cases.

@ldcornell @sam_albadri @Renalpathsoc We have not yet started. But see potential value. I like the idea of "diagnosis" agnostic indices.

Insightful session on incorporating Activity & Chronicity Indices into the Banff classification for kidney allograft biopsies. Standardizing inflammation and chronic injury scoring may enhance prognostication and therapeutic decisions. Kudos to Dr. Serena Bagnasco and Dr. Muthukumar for an excellent, thought-provoking lecture 👏 Are you currently integrating Activity/Chronicity indices into your renal pathology reports? If so, how has it influenced clinical management? #Banff #RenalPathology #KidneyTransplant #Nephrology

Nice example of pigmented nephropathy (likely myoglobin cast nephropathy) in an autopsy case (sepsis). I find this is a frequently overlooked finding in autopsy cases. Trichrome highlights the casts bright red. Can also do myoglobin stain to confirm. #renalpath #autopsypath

@shary_tang @JZRenalPath pubmed.ncbi.nlm.nih.gov/12605360/ is this the lesion you’re referring to? Mark Haas had a nice paper on it!

@JZRenalPath Singular subepithelial EDD laden with spherions are commonly seen at the folds of the GBM near mesangial area. Infection related?

Rare thin GBM segments can be seen cases of advanced diabetic glomerulopathy (1-5% of surface areas); otherwise thickened GBM. Thought to represent new vessel formation; not to be confused for COLIV related disease. #renalpath #nephrology #pathtwitter pubmed.ncbi.nlm.nih.gov/2456298/

Why is IgG4-related kidney disease overlooked or misdiagnosed? #renalpath @Renalpathsoc @VuMedi @IgG4ward #IgG4 vumedi.com/video/why-igg4…

Not all glomerular disease is the same. Yet many kidney transplant trials still exclude these patients altogether. Fresh off the press! kireports.org/article/S2468-…

Reminder to review non-neoplastic tissue in tumor nephrectomies. #renalpath always takes a quick look here. Slightly tedious but can be very useful. RCC pt with amyloidosis. Amyloid A IHC positive (can be seen with RCC); mass spec pending. #nephrology #pathwitter #nephrology

UCalgary claims top five spot in national research rankings. How does this impact you and your community? ucalgary.ca/top-five

@shary_tang @yaelheher had the thought that it could be cartilage!

@ldcornell Many thanks, will do endothelial and neurobiological marker staining

29y male，body builder, 1-1.7g proteinuria, Alb normal, Scr slightly increased (92.9-97.2-100.3) umol/L. LM: 2 glom with FSGS lesion, but what is the pie-like granular lesion in interstitium? #renalpath #askrenalpath

@NateSilver538 Now ChatGPT (-5) can sometimes give you an actual scientific literature reference whereas before all references were completely made up

If you use LLMs like ChatGPT, Claude, Gemini or Grok regularly, how would you rate their overall performance on tasks you routinely use them for, as compared to ~1 year ago?

@AstridWeins @ChangUCanSpare @Nephro_Sparks @janewitwong I also have never used it as a pathologist! I always thought of it as basically a clinical term like RPGN.

@Nephro_Sparks @janewitwong @ChangUCanSpare I have never used the term hypertensive nephrosclerosis in my life as a renal pathologist. It is literally banned on my service. For the book we had to compromise - a few steps at a time. I you read what is in the chapter, I hope you can see Tony’s efforts shine through! :-)

The 11th edition of the classic pathology textbook Robbins/Cotran/Kumar Pathologic Basis of Disease is out! Just received my brand new copy. Honored to have joined forces with @ChangUCanSpare to rewrite and update the kidney chapter.

@hemepathguy Wow

#hemepath Interesting case...kidney biopsy

Registration for the 6th IRP Conference is open! Registration & abstract info: 👉renalpathsoc.org/6thIRPC On behalf of the 6thIRPC Organizing Committee, Dr. Carmen Avila-Casado, Chair 6th IRPC Dr. Vicente Sanchez-Polo, President SLANH #renalpath

Recently, misinformation about organ #donation surfaced. I’m an organ donor and proud caregiver to transplant recipients. More than 90,000 people are waiting for a kidney, and half will die before getting one. The shortage is real. Sign up to be an organ donor #DonationSavesLives
