IHC Talk: TRBC1 in T-cell Lymphomas

The Chromogen Siblings are back to talk about TRBC1 IHC in T-cell Lymphomas! Dr. Mike Arnold (@MArnold_PedPath [https://x.com/MArnold_PedPath]),  Dr. Andrew Bellizzi (@IHC_guy [https://x.com/IHC_guy]), and Dr. Sanam Loghavi (@sanamloghavi [https://x.com/sanamloghavi]) speak with Dr. Pranav Patwardhan and Dr. Erika Moore of the University of Pittsburgh Medical Center about their publication in the American Journal of Surgical Pathology: The Utility of TRBC1 Immunohistochemistry in the Evaluation of T-Cell Lymphomas [https://journals.lww.com/ajsp/abstract/9900/the_utility_of_trbc1_immunohistochemistry_in_the.563.aspx].  Hear about the Hematopathology practice in different institutions, and the challenges in diagnosing T-cell lymphomas. We also hear about how Hematopathologists can use TRBC1 IHC to identify clonal populations of T-cells to support the diagnosis of T-cell lymphoma.   Featured article:  The Utility of TRBC1 Immunohistochemistry in the Evaluation of T-Cell Lymphomas https://journals.lww.com/ajsp/abstract/9900/the_utility_of_trbc1_immunohistochemistry_in_the.563.aspx [https://journals.lww.com/ajsp/abstract/9900/the_utility_of_trbc1_immunohistochemistry_in_the.563.aspx]   Featured public domain music: Alpha Hydrae, Won't see it comin' [https://freemusicarchive.org/music/Alpha_Hydrae/uu_/Alpha_Hydrae_-_Alpha_Hydrae_-_uu__-_10_Wont_see_it_comin_Feat_Aequality__Nsorte_dautruche]

Around The Scope: Prostate Pathology

In this series, PathPod gathers pathologists and trainees Around The Scope to discuss their work in depth. Today, we hear about prostate pathology and how optimization of Gleason grading can improve prognostic information. Our hosts, Dr. Mike Arnold (@MArnold_PedPath [https://x.com/MArnold_PedPath]) and Dr. Andrew Bellizzi (@IHC_guy [https://x.com/IHC_guy]) talk with Dr. Jesse McKenney, Dr. Jane Nguyen (@janenguyen44 [https://x.com/janenguyen44]) and Dr. Sean Williamson (@Williamson_SR [https://x.com/Williamson_SR]) of the Cleveland Clinic. Hear about how PSA screening changed the biopsies that pathologists see, and how the art and science of re-examining Gleason grading refined prognosis for patients with prostate cancer.   Featured articles: Histologic Grading of Prostatic Adenocarcinoma Can Be Further Optimized Analysis of the Relative Prognostic Strength of Individual Architectural Patterns in 1275 Patients From the Canary Retrospective Cohort: https://pubmed.ncbi.nlm.nih.gov/27635949/ [https://pubmed.ncbi.nlm.nih.gov/27635949/] Correlation of large cribriform carcinoma and "unfavorable histology" with other Gleason pattern 4 subtypes: A proof-of-principle study evaluating 485 radical prostatectomy specimens with proposal for the concept of "borderline histology": https://pubmed.ncbi.nlm.nih.gov/39644729/ [https://pubmed.ncbi.nlm.nih.gov/39644729/] Proposal for an optimised definition of adverse pathology (unfavourable histology) that predicts metastatic risk in prostatic adenocarcinoma independent of grade group and pathological stage: https://pubmed.ncbi.nlm.nih.gov/38828674/ [https://pubmed.ncbi.nlm.nih.gov/38828674/] Classification of prostatic adenocarcinoma as favourable/unfavourable histology has high interobserver agreement in prostate needle core biopsies: https://pubmed.ncbi.nlm.nih.gov/40762236/ [https://pubmed.ncbi.nlm.nih.gov/40762236/]   Public domain music: Main Stem by US Army Blues [https://freemusicarchive.org/music/US_Army_Blues/Live_At_Blues_Alley/0_-_02_-_The_US_Army_Blues_-_Main_Stem]

PathPod Listens to the People of Pathology Podcast with Dennis Strenk

In this episode, host Dr. Michael Arnold (@MArnold_PedPath [https://x.com/MArnold_PedPath]) speaks with Dennis Strenk (@dstrenkpa [https://x.com/dstrenkpa]), Pathologists' Assistant at Wisconsin Diagnostic Laboratories, about the podcast he started in 2019, the People of Pathology [https://peopleofpathology.podbean.com/] podcast. Hear about how he got started as a Pathologists' Assistant and what got him interested in starting the People of Pathology [https://peopleofpathology.podbean.com/] podcast. Hear what he enjoys about podcasting and what he's learned. We also celebrate the 200th episode of the People of Pathology Podcast by listening to a special episode he selected. Hear about what he learned making episode 38 of the podcast, and how the connection he made with his guest, Dr. Ralph Hruban, continued in person.     You can read more about Dennis Strenk and the People of Pathology Podcast in his recent profile in The Pathologist [https://thepathologist.com/issues/2025/articles/july/love-the-lab-podcast-it/]magazine.   Featured public domain music: Main Stem by US Army Blues [https://freemusicarchive.org/music/US_Army_Blues/Live_At_Blues_Alley/0_-_02_-_The_US_Army_Blues_-_Main_Stem]

Around The Scope: Social Media

In this series, PathPod gathers pathologists and trainees Around The Scope to discuss their work in depth. Today, we hear about social media, from #PathArt to TikTok. Our hosts, Dr. Sara Jiang (@Sara_Jiang [https://twitter.com/Sara_Jiang]) and Dr. Mike Arnold (@MArnold_PedPath [https://x.com/MArnold_PedPath]) speak with Dr. Meredith Herman (X: @MeredithKHerman [https://x.com/MeredithKHerman] TikTok: @meredithkherman [https://www.tiktok.com/@meredithkherman]) and Julia Kochanowski (TikTok: @myforensicpath [https://www.tiktok.com/@myforensicpath]) about now pathology and medical education on social media is changing.

IHC Talk: Small Cell Lung Carcinomas with Dr. Natasha Rekhtman

The Chromogen Siblings return to talk about small cell lung carcinomas. Drs. Mike Arnold (@MArnold_PedPath [https://x.com/MArnold_PedPath]),  Andrew Bellizzi (@IHC_guy [https://x.com/IHC_guy]), and Sanam Loghavi (@sanamloghavi [https://x.com/sanamloghavi]) speak with Dr. Natasha Rekhtman (@natasharekhtman [https://x.com/natasharekhtman]) of Memorial Sloan Kettering Cancer Center.
