Grading Melanocytic Dysplasia: Updated Histopathologic Criteria

Journal of Cutaneous Pathology, Volume 53, Issue 1, Page 29-37, January 2026.
ABSTRACT Dr. Martin C. Mihm, Jr.'s innovative work on the dysplastic nevus achieved a milestone in his chapter in the World Health Organisation Classification of Skin Tumours (WHO‐C). WHO‐C presents a dichotomous classification (high‐grade versus low‐grade dysplastic nevi) and a quantitative metric to assess melanocytic nuclear enlargement.

Chromatin folding by the Polycomb group proteins and its elusive role in epigenetic repression

The FEBS Journal, Volume 293, Issue 1, Page 10-25, January 2026.
Genes repressed by the Polycomb system display greater chromatin folding compared to ‘regular’ inactive genes. The associated chromatin compaction, driven by PRC1‐H3K27me3 interactions, is modest and dynamic. This questions traditional models where Polycomb proteins repress transcription by sheltering genes from transcriptional activators.

Treatment‐related changes in the prostate: past, present and future therapies

Histopathology, Volume 88, Issue 1, Page 40-52, January 2026.
Radiation therapy alters tumour morphology and immunoprofile in prostate cancer. Residual carcinoma shows distorted glandular architecture on H&E and loss of basal markers with preserved AMACR expression by immunohistochemistry, aiding in the recognition of treatment effect in prostate biopsies.
