Finally, a histologic biomarker for USP6-associated tumors, led by Margarita Muñoz de Toro @StanfordPath: pubmed.ncbi.nlm.nih.gov/4285… A new technique also highlighted in the excellent recent work by Dinh et al: pubmed.ncbi.nlm.nih.gov/4250… #BSTpath

Dedifferentiated and undifferentiated melanomas remain underrecognized with significant treatment implications - @aubre_gilbert shows that PD-L1 can provide a useful diagnostic hint (not just a predictive marker!). @StanfordPath @JHUPath
New in #HumPathol: Sarcomatoid malignancies with strong PD-L1 expression often represent dedifferentiated or undifferentiated melanomas. sciencedirect.com/science/ar… #pathology #PathTwitter #PathX #BSTpath

Expanding the genetic spectrum of PKC-fused blue nevi. They are however recognizable by morphology and IHC alone. If you practice dermpath you will encounter these frequent benign tumours. Follow the link for temporary free access to our most recent paper authors.elsevier.com/a/1ntUQ…

A highy informative manuscript (from our 2027 Annual Review Issue on dermatopathology) tackling the challenging topic of cutaneous drug reactions and focusing on systemic anti-cancer therapies. The illustrations are helpful and clear. #dermpath #Xpath doi.org/10.1111/his.70286

Need an update on the molecular pathology of bladder cancer? I am delighted to share a comprehensive review article by Dr. Antonio Lopez-Beltran and colleagues, published in the 2026 Annual Review Issue of Histopathology @Histo_Journal @daniel_berney
🔗 Article: onlinelibrary.wiley.com/doi/… Advances in molecular classification, biomarker development, and personalized therapies are transforming the management of bladder cancer. The rapid expansion of therapeutic targets - together with ongoing clinical validation—underscores the essential role of pathologists, as pre-analytical and analytical considerations directly impact the approval, adoption, and optimal use of new cancer drugs. Integrating molecular and morphologic data into routine pathology reporting will be critical to support clinical decision-making and enable precision-based treatment. Molecular classification remains a rapidly evolving research area with major potential to reshape clinical practice. The marked molecular and morphological heterogeneity of urothelial carcinoma presents challenges, but also offers opportunities to refine patient stratification and tailor therapeutic interventions. Emerging liquid-based biomarkers—including circulating tumor DNA (ctDNA) and urinary tumor DNA (utDNA)—show strong promise for detecting minimal residual disease, monitoring treatment response, and assessing disease dynamics in a minimally invasive manner. For more GU-focused reviews, the full 2026 Histopathology Annual Review Issue (Special GU Edition) is available here:
