Renal Primitive Neuroectodermal Tumors [PDF]

Archives of Pathology & Laboratory Medicine, 2012
Primitive neuroectodermal tumors exist as a part of the Ewing sarcoma/primitive neuroectodermal tumor family. These tumors most commonly arise in the chest wall and paraspinal regions; cases with a renal origin are rare entities, but have become increasingly reported in recent years. Although such cases occur across a wide age distribution, the average

Integrated high‐resolution copy number and histomolecular analysis of diffuse hemispheric glioma, H3 G34‐mutant reveals universal TP53 abnormalities

Brain Pathology, Volume 36, Issue 4, July 2026.
This integrated high‐resolution copy number and histomolecular analysis of diffuse hemispheric glioma, H3 G34‐mutant expands the spectrum of associated genetic changes and underscores the presence of universal TP53 abnormalities at copy number, sequence, and protein expression level, with frequent yet largely unrecognized TP53 copy‐neutral loss of ...

Concomitant Medication Effects on Immunotherapy Outcomes in Sarcoma: A Pooled Post Hoc Analysis of Seven Phase II Trials

Cancer Medicine, Volume 15, Issue 6, June 2026.
ABSTRACT Background Concomitant medications (CMs) influence outcomes in patients receiving immune checkpoint inhibitors (ICIs), but their impact in sarcoma remains undefined. We assessed the association between CM use and ICI outcomes in patients with advanced or metastatic sarcoma. Methods This pooled analysis included patients from seven investigator‐

Clinicopathological Features and Postoperative Complication Management of a Postauricular Granular Cell Tumor: A Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Postauricular granular cell tumors mimic parotid malignancies. Their resection disrupts fragile local microcirculation due to inherently thin skin and limited subcutaneous buffer, triggering ischemic necrosis and MRSE infection. Clinicians must prioritize functional tissue preservation and vigilant wound care to prevent these severe ...

Generation and Characterization of Twist1 Acetyl‐Mimic and Acetyl‐Deficient Mouse Models

genesis, Volume 64, Issue 3, June 2026.
ABSTRACT TWIST1 encodes a highly conserved basic helix–loop–helix transcription factor essential for embryonic development from Drosophila to humans. TWIST1 activity is regulated by post‐translational modifications, including phosphorylation during development and cancer metastasis. Recent cancer studies identified acetylation of lysines K73 and K76 as
