Acquired cystic disease of the kidney lesions #GUPATH: A Thread 👇 Grossing is important ✅Describe and sample all solid or partly solid lesions separately. ✅Include location, size, & distance from other lesions ✅Pay attention for involvement of perinephric and renal sinus

The @Pathologists Cancer Committee and #CPDS staff meet again in San Francisco, CA, with this working meeting focusing on optimization of cancer protocols. We are united in our mission to advance cancer care one cancer #protocol at a time! #pathology #pathtwitter

Thanks to all who responded! PIN-like PCA 33=6, GG1 🛑⚡️don't brush off as HGPIN-can be tricky on needle biopsies Used to be called HGPIN-like ductal PCA but now re-classified as acinar References: PMID 35758185 & 29297491 #GUPATh #pathology #pathres

Thanks to all who responded! I favored minute focus of PCA 3+4, with comment that assessing percentage of Gl4 is difficult in small foci ⚡️🛑 Sharing to highlight the spectrum of interpretation for small foci like this & danger of over-Gleason scoring them #gupath #pathology

Single focus in well sampled #prostate (including snapshots of levels) How far would you go ASAP vs PCA Gleason Score? #GUPATH #pathology #pathres

What is your diagnosis? #prostate #gupath #pathology #pathres

Prostate cancer w/foamy gland features - note the pyknotic nuclei in foamy glands = deceptively benign-appearing Fortunately, as in this example, often admixed with usual acinar #prostatecancer with more amphophilic cytoplasm, prominent nucleoli, etc. #gupath

Awesome of @AcquiredFM to track down my 2001 thesis at @google that compression is understanding!

Was great fun to educate with and learn from Drs. Lara Harik, Francesca Khani, & Jesse McKenney at the #CAP25 GU Pathology Long Course- thanks @KAMitchellR and @Pathologists Education Cmte for the opportunity!

The #gupath Long Course launches 🚀 tomorrow, Tuesday 9/16 at #CAP25 - join us to learn about and how to address Diagnostic Challenges in Prostate, Bladder, & Kidney Cancer! @Pathologists @LaraHarikMD @FKhaniPath

I'm excited to speak at the Kidney Cancer Association's upcoming Virtual Patient Symposium on September 6! Join other kidney cancer patients and caregivers for a day of learning. Register here: https://t.co/Jjt0Ljalmh. @KidneyCancer @KCPUTSW @utswcancer @UTSW_Pathology

Thrilled to be joining Drs. Lara Harik, Francesca Khani, and Jesse McKenney for the #gupath Long Course at #cap25 in Orlando 9/16/2025 Join us to explore Practical Approaches to Contemporary Diagnostic Challenges in Kidney, Bladder, and Prostate Cancer @Pathologists

@Kiril_T_Can @GTumors @Williamson_SR @MichelleDunno17 Not sure how to edit this post: the name has recently changed to clear cell papillary renal cell tumor; a nod to its indolent behavior

Abrupt transition from low to high nuclear grade in this Clear Cell Renal Cell Carcinoma #gupath #kidneycancer - highlighting the importance of sampling

Enjoy 2 excellent webinars discussing histological staging of bladder cancer with this link: https://t.co/xhtJQtK28E Eminent uropathologists Eva Comperat, Antonio Lopez-Beltran, Priya Kunju and Lara Harik outline their approach to resolving thorny staging issues.

In some Clear Cell RCC, when tumor becomes higher grade, cells become discohesive➡️'pseudo-papillary' appearance #kidneycancer #gupath In biopsies, this feature and variable clear to eosinophilic cytoplasm may raise a differential diagnosis which includes MiTF -family RCC

Coarse eosinophilic granules (so-called 'Paneth-like') can be seen in all grades of #prostatecancer #gupath Unlike true Paneth cells [GI tract], these cells are neuroendocrine marker (+), do NOT contain lysozyme

Invasive adenocarcinoma (bladder) in a background of adenomatous change with dysplasia 🚫evidence of urothelial carcinoma (in situ/invasive) Reporting Comment: "We would accept this tumor as primary to this site in direct extension or metastasis from other sites can be excluded"

Can you spot the subtle differences in urinary bladder pathology? Put your skills to the test during this case-based CME webinar on flat and papillary bladder lesions. Don't miss out, register now! https://t.co/dzovlrz9y5
