There were also mesangial IgA deposits (Figure 3), which likely explain the patient's hematuria and proteinuria, since there was very little glomerular amyloid (Figure 4).

The stain is a Congo Red viewed under fluorescent light with a red filter. It highlights interstitial amyloid deposits, which is the predominant pattern of deposition in LECT2 amyloidosis (confirmed by IHC stain, Figure 2).

Autolysis versus ATN in an autopsy specimen. Autolytic tubules show detachment of epithelial cells from tubular BM and seem to fall off into the lumen (yellow circle). Rest of tubules with ATN: epithelial cells on the BM but thin + loss of brush borders. #renalpath #pathsky
1/ This electron microscopy shows marked GBM abnormalities, consistent with Alport's Syndrome (AS). The patient had genetic testing, which confirmed a COL4A3 mutation.

Allograft biopsy for AKI after belatacept conversion. Yikes! Acute cellular rejection grade III with necrotizing arteritis. #renalpath #pathsky #nephsky
We're excited to share a new research publication from @aaronstorey.bsky.social, @glombandit.bsky.social, and Dr. Chris Larsen titled, "Proteomic Profiling of Complement Components in Glomerular Disease."

Some large KW nodules in this case of diabetic nephropathy. Unfortunately a common occurrence in my biopsy practice. #renalpath #pathsky #nephsky
Another chronic glomerulopathy case. EM stage IV of IV resorbed deposits in a pt with PLA2R+ Membranous nephropathy with persistent proteinuria. #renalpath #pathsky #nephsky
1/ The biopsy shows collapsing glomerulopathy, for which the differential diagnosis in a transplant recipient includes ischemia, calcineurin inhibitor nephrotoxicity, CMV infection, thrombotic microangiopathy, and donor-derived APOL1-associated nephropathy.

Figure 1 Hematoxylin andeosin–stainedrenal biopsy(original magnification ×40) of the patient showingtubulointerstitial nephritis, characterized by a mononuclear inflammatory infiltrate with clusters ofmacrophages containing round intracytoplasmic structures (highlighted by the black circle). The Grocott-stained specimen (see Supplementary Figure S1) revealed intracytoplasmic round structures consistent with Histoplasma capsulatum yeasts. These histologic features supported the diagnosis of interstitial nephritis by Histoplasma spp. (see Supplementary Figure S1 for the differential diagnosis discussion).
Supplementary Figure S1. Grocott-stained specimen demonstrating intracytoplasmic round structures consistent with Histoplasma capsulatum yeasts (indicated by the red arrow). The differential diagnosis with other fungi (such as Cryptococcus, Candida, Blastomyces, and Paracoccidioides) and other intracellular pathogens (such as Toxoplasma, Leishmania, and Trypanosoma) was made based on the following histopathologic features: small size (2–5 μm), round shape, homogeneous intracellular distribution, silver positivity, absence of kinetoplasts, and negative mucicarmine staining—all of which supported the diagnosis of histoplasmosis.

Recent bxs are so important for clinical trial enrolment. Bx in pt with hx of lupus nephritis (IV+V) with worsening proteinuria. Bx for trial enrollment. Chronic changes only, 0 activity, resorbed deposits by EM, min IF staining. #nephsky #renalpath #Pathsky

Bx in older F pt for subnephrotic proteinuria reveals numerous myelin figures in podocytes. Concern for Fabry + other genetic diseases. Subsequently learned the pt was on long term to Plaquenil. Genetics pending, but may all be HCQ tox. #renalpath #pathsky #nephsky

The PAS-stain picture depicts gray and basophilic amorphous material within glomerular capillaries, consistent with polymer emboli. The patient had undergone renal transplant artery angioplasty a few months earlier.

What happens when oxalate nephropathy & renal embolic disease interact? How does this interaction impact kidney function? Find out the answer in our latest #Collidescope episode!
#renalpath #kidneypath #pathsky #renalsky
In this week's #Collidescope case, Dr. Charles investigates a case of oxalate nephropathy & renal embolic disease. Watch the episode to learn more about how these two diseases interact and affect kidney function.

The biopsy shows linear IgG staining along the GBM, and extensive fibrinogen staining within the Bowman space, consistent with crescent formation. These findings are diagnostic of anti-GBM disease.

Somewhat subtle case of light chain cast nephropathy by LM. Mostly fine granular casts. Rare PAS pale + two toned color casts. No cellular reaction. IF with K restricted casts confirmatory. EM demonstrates LC precipitation with uromodulin. #renalpath #nephsky #pathsky
Interesting case of necrotizing vasculitis in a lupus patient. Hx of LN in prior biopsies, no active GN features now. May be lupus vasculitis, but recommend r/o superimposed vasculitic disease (e.g., ANCA, drugs) with such biopsies findings. #renalpath #nephsky #pathsky
Tumor nephrectomy with incidental ALECT2. Interestingly this was from a pt from India. Reminder that a subset of ALECT2 cases have been reported in Punjabi patients (pubmed.ncbi.nlm.nih.gov/35986199/) . #renalpath #pathsky #nephsky
Leucocyte tickling a tubular epithelial cells in a case of cellular rejection in a txp biopsy. Can anyone with more immunology knowledge than me explain what is happening here? #renalpath #nephsky #pathsky
1/ Answer: Focal and Segmental Glomerulosclerosis, Favor Secondary.
The biopsy shows sclerosis involving a portion of the glomerular tuft (segmental) of some, but not all, glomeruli (focal).
