Primary Pulmonary Mesenchymal Neoplasm With EWSR1::CREM Fusion: Cytologic Findings and Molecular Diagnosis

Diagnostic Cytopathology, EarlyView.
ABSTRACT Background Primary pulmonary mesenchymal neoplasms with EWSR1::CREM fusion are rare. These lesions are challenging to diagnose by morphology and immunohistochemistry alone. Case A 66‐year‐old woman (ex‐smoker) was found to have a 1.3‐cm right lower lobe lung nodule that had grown very slowly over a 9‐year period.

Mapping the Tissue Architecture and Endothelial‐PEC Network in HAML Using Single‐Cell and Spatial Transcriptomics

Cancer Science, EarlyView.
Spatial multi‐omics mapping of hepatic angiomyolipoma reveals that PEComas tightly co‐localize with endothelial cells, which drive autophagic flux in adjacent tumor cells via a paracrine PDGFD–PDGFRB–Ras axis, establishing a compensatory survival network that operates in parallel to canonical TSC–mTOR defects.

Out of the Ordinary, but Not Out of the Question: Atypia in Pancreatic Lesions Is Not Always Carcinoma

Cytopathology, EarlyView.
An incidental pancreatic lesion in a 69‐year‐old woman was sampled by EUS‐guided fine‐needle biopsy. Integrated cytopathological and histopathological evaluation with immunochemical staining supported organ‐preserving surgery. ABSTRACT Pancreatic perivascular epithelioid cell tumours (PEComas) are exceptionally rare mesenchymal neoplasms.
