Multi-focal severe necrotizing arteritis in a kidney biopsy with an ANCA vasculitis. Interestingly, foci of arteritis were only present in IF/EM tissue. Illustrating how even when severe arteritis can be easily missed due to sampling in a small biopsy. #renalpath #nephsky #pathsky

Course Director Dr. Alexandros D. Polydorides provided this quick case overview for us.

Clinical history: 67 F with prior appendectomy, now presenting with an implant in the mesentery of the jejunum.

Excuse the “taking a picture of a computer screen” quality here - this looks like early MN pattern (IgG, IgG1 here) by IF, but EM has absolutely no deposits (EM on frozen material done on this glom). Still MN (“by IF only”?!)? @glombandit.bsky.social @arkanalabs.bsky.social @jzrenalpath.bsky.social

We are looking for a 3rd renal pathologist to join our team here at UCLA. Please see the job description here: recruit.apo.ucla.edu/JPF10146. It's a great department and LA is a great city. #renalpath #pathsky

A polyoma virus 'crescents' in a case of BK nephropathy in a kidney transplant patient. SV40 demonstrates parietal epithelial cell positivity on deeper levels. BK viremia >3 million recently. #renalpath #pathsky #nephsky

Rovin et al get the 2nd kidney bx in this lupus nephritis study using voclosporin and did not find CNI toxicity

A cute finding in apocrine metaplasia, do you know what it is? #breastpath #pathsky #pathtwitter #pathx #patologia

Pronase IF can be very helpful in cases of cryo-GN as the frozen IF is often masked. This case also showed classic hyaline pseudo-thrombi, cryo-vasculitis, and microtubules by EM. #renalpath #pathsky #nephsky

Several CDC websites and datasets related to HIV, LGBTQ people, youth health behaviors and more have been removed after the agency was directed to comply with an executive order from President Donald Trump.

As an expert on death, I’m stating the obvious by saying #DEI has no role in air traffic fatalities.

Also, aviation is one of the least diverse professions - <5% of commercial pilots are women and >90% of pilots and flight engineers are from non-ethnic backgrounds.

Yet another baseless claim..😒

What I'm looking for in #placenta membranes:
MVM incl
. Decidual arteriopathy
. Mural hypertrophy
. Atherosis and fibrinoid necrosis

Maternal inflammatory response stage 2, acute chorioamnionitis - more than a few neutrophils in the fibrous chorion and amnion. I need to see subchorio as well.

Example of necrotizing lupus vasculopathy. Hilar arterioles with luminal immune complex deposit and mural necrosis. Ig deposition in lumen of vessel and fibrinogen staining by IF. #renalpath #pathsky #nephsky
