Ossifying spindled and epithelioid tumour: Expanding the clinical and morphologic spectrum of a recently described entity

open access: yesHistopathology, Volume 89, Issue 1, Page 163-173, July 2026.
Ossifying spindled and epithelioid tumour (OSET) can show unusual morphologic features, including minimal or absent peripheral ossification, eosinophil‐rich stroma, increased mitotic activity (≥5 mitotic figures per 10 high‐power fields), and necrosis.

Antibiotics in Veterinary Ophthalmology: Resistance, Stewardship, and Emerging Antibiotic‐Sparing Strategies

open access: yesVeterinary Ophthalmology, Volume 29, Issue 4, July 2026.
ABSTRACT Antimicrobial resistance (AMR) is a growing challenge in veterinary ophthalmology, particularly in cases of bacterial keratitis, where progressive stromal infection can threaten vision and globe integrity within hours to days. This review synthesizes current evidence on pathogen distribution, antimicrobial susceptibility profiles, multidrug ...

MYCN Amplification in RB1‐Inactivated Retinoblastoma: Association With High‐Risk Features

open access: yesPediatric Blood &Cancer, Volume 73, Issue 6, June 2026.
ABSTRACT Background MYCN amplification occurs in a subset of retinoblastoma cases, both with and without RB1 inactivation. It has been suggested that retinoblastomas with MYCN amplification represent a distinct entity with more aggressive clinical behavior.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, Volume 20, Issue 6, Page 1429-1452, June 2026.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Association of CDKN2A/B Homozygous Deletion and Extent of Resection With Survival of Patients With WHO CNS5 Grade 4 Astrocytoma

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 6, Page 1258-1267, June 2026.
ABSTRACT Objectives WHO grade 4 astrocytomas are associated with poor prognosis, and their prognostic factors remain controversial. This study aimed to identify the prognostic factors and develop a management algorithm for these patients. Methods This study retrospectively included 151 CNS5 adult grade 4 astrocytomas from two medical centers.
