Clinical and molecular features of primary gliosarcoma with digital spatial whole‐transcriptome analysis of glial and mesenchymal components

Brain Pathology, Volume 36, Issue 5, September 2026.
We report the clinical and genetic features of an institutional cohort of primary adult gliosarcomas compared to glioblastoma. We performed spatial whole‐transcriptome analysis on glial and sarcomatous regions of four cases to compare gene expression profiles and validated differential protein expression for two markers in tissue sections.

Eccrine Squamous Syringometaplasia Mimicking Acute Cutaneous GVHD in a Pediatric HSCT Recipient: Case Report and Brief Review of the Indexed Literature

Journal of Cutaneous Pathology, Volume 53, Issue 9, Page 792-802, September 2026.
ABSTRACT Eccrine squamous syringometaplasia (ESS) is an uncommon reactive alteration of eccrine ducts, most often reported in oncologic and transplant settings, where it may clinically mimic acute cutaneous graft‐versus‐host disease (GVHD). We describe a 3‐year‐old boy with chronic granulomatous disease who developed a diffuse erythematous eruption 6 ...

Intramuscular myxoma with chondroid features: two cases expanding the morphological spectrum

Histopathology, Volume 89, Issue 3, Page 554-557, September 2026.
Background Intramuscular myxoma is a benign mesenchymal tumour typically composed of bland spindle to stellate cells in abundant myxoid stroma and usually characterized by GNAS mutations. Chondroid matrix has not been previously reported in intramuscular myxoma.

The 2025 ATS/ERS update of the international multidisciplinary classification of the interstitial pneumonias: implications for the pathologist

Histopathology, Volume 89, Issue 3, Page 403-425, September 2026.
This review highlights changes relevant to pathologists in the updated multidisciplinary classification of interstitial pneumonias. Changes include expansion beyond idiopathic disease, subclassification as interstitial (fibrotic vs non‐fibrotic) and alveolar filling disorders, expansion to include additional patterns (e.g.

Unveiling the molecular profile of adenosquamous gallbladder carcinoma: characterization of a Caucasian cohort

Histopathology, Volume 89, Issue 3, Page 442-455, September 2026.
GBASCs are MMRp tumours, exhibiting minimal HER2 overexpression and elevated PD‐L1 expression compared to adenocarcinomas. Especially in metastatic and TP53‐wild type tumours, GBASCs can express CLDN18, albeit limited to the glandular component. Their genomic profile resembles that of adenocarcinomas with an enrichment in alterations on PIK3CA, PTEN ...

Dose‐Dependent Reprogramming of Chromatin Accessibility by SOX4 Drives the Transcriptional Response to Iron Overload

Advanced Science, Volume 13, Issue 43, 3 August 2026.
This study demonstrates that iron overload triggers widespread chromatin compaction and transcriptional repression in human granulosa cells, recapitulating features of endometriosis. The epigenetic reprogramming is orchestrated by a TFEB‐SOX4‐SWI/SNF axis, with SOX4 acting as a central, dosage‐sensitive regulator.

Deceptive Thyroid Pathologies: Anaplastic Thyroid Carcinoma Mimics and Clinical Implications

Head &Neck, Volume 48, Issue 8, Page 2180-2189, August 2026.
ABSTRACT Background Beyond follicular‐derived thyroid carcinomas, lymphomas, and metastatic disease, there are rare pathologies of the thyroid gland that represent a challenge. We report patients with unusual malignancies that mimic similar aggressive cancers. Methods Retrospective case series.
