Excited to see that our paper was selected as the Editor’s Choice for the current issue in the Journal of Clinical Pathology!

Eosinophilic Vacuolated Tumor (EVT) - generally considered benign/indolent & associated with MTOR pathway mutations. However, rarely it can be seen w/metastatic dz, as seen here (LVI+, LN+). 🔬@GU_Path_Society @IntSocUropath @AdanmaAnjiMD @Kiril_T_Can https://t.co/kVO6K2Bccu

I couldn't attend last year's USCAP due to my 🇨🇦 board exam happening on the same week, but I'm thrilled to be going to USCAP 2026, in San Antonio! Honoured to have 3 accepted abstracts with Dr. Michelle Downes and 2 with Dr. Ankur Sangoi @slusagar! #GUpath @UofT @StanfordPath

Do you know how to FISH? I am delighted to share our 20+ years of experience with FISH, just published in @Human_Pathology (PMID: 40782985) -  Everything You Need to Know About FISH! This comprehensive review covers the full spectrum of fluorescence in situ hybridization (FISH)

Interesting case to share  (Board question): What's your diagnosis for this 3.3 cm renal tumor from a 42-year-old man? Vimentin, SMA, CD34, and CD10 are positive. Electron microscopy reveals electron-dense, rhomboid-shaped crystals in the cytoplasm.

Very pleased to share an online piece brought to you by the CAP Personalized Health Care Committee. By Dr. Maria Del Carmen Rodriguez Pena and yours truly. IHC in soft tissue tumor pathology! https://t.co/g15khkZyM3 #PathTwitter #molpath #surgpath #BSTpath @Pathologists

Excited to begin my final year of residency in Diagnostic and Molecular Pathology (Anatomical Pathology) at @UofT, and honoured to serve as a Chief Resident from July to December. Grateful for the opportunity, and looking forward to continued learning and collaboration!

Let’s do IHC for #OnePicDx! 🔍 Based on PIN4 staining, what is your diagnosis on this #prostate neoplasm? a. Acinar adenocarcinoma b. Prostatic intraepithelial neoplasia (PIN) c. Ductal adenocarcinoma d. PIN-like carcinoma Answer in comment 👇👇👇 #GUPath

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

Illustration of von Brunn nests in upper tract...tend to be smaller and either closely aligned or horizontally / linearly aligned to overlying urothelium - can occasionally present a diagnostic dilemma, esp. in small specimens, as highlighted here: https://t.co/xsOtEcnRB9 #gupath

adult human presents with hematuria, bladder mass found, TURBT performed #GUpath🤨

Low power view diagnosis of this renal mass with distinctive morphology? #GUPath #OnePicDx Answer is all in the picture👇
