AOSNP‐ADAPTR resource level‐based recommendations on practical diagnostic strategies for medulloblastomas and other embryonal tumors

Brain Pathology, EarlyView.
Resource level‐based recommendations on practical diagnostic strategies for medulloblastomas and other CNS embryonal tumors are provided. Abstract WHO CNS5 mandates integrated histo‐molecular classification of medulloblastomas (MBs) and other CNS embryonal tumors. However, advanced molecular diagnostics remain inaccessible in many low‐ and lower‐middle‐

HierAnom‐Path: Zero‐Shot Rare Cancer Detection in Histopathology via Hierarchical Foundation Model Adaptation

Computational and Systems Oncology, Volume 6, Issue 1, December 2026.
ABSTRACT Rare cancers collectively represent 20%–25% of all malignancies yet yield fewer than 50 annotated whole‐slide images (WSIs) per subtype in publicly available archives, rendering supervised deep learning inapplicable. We present HierAnom‐Path, to the best of our knowledge, the first framework for zero‐shot rare cancer anomaly detection in ...

Outcomes of adult patients with Li‐Fraumeni syndrome and myeloid neoplasms

Cancer, Volume 132, Issue 19, 1 October 2026.
Abstract Background Li‐Fraumeni syndrome (LFS) is an inherited cancer predisposition syndrome. Hematologic malignancies are not considered LFS defining tumors, however, both acute lymphoblastic leukemia and therapy‐related myeloid neoplasms (MNs) in LFS are described. Treatment approaches and outcomes of MN in LFS need further evaluation.

Molecular and Proteomic Profiling of Human Cerebral Organoid‑Derived Small Extracellular Vesicles

Developmental Neurobiology, Volume 86, Issue 4, October 2026.
ABSTRACT Organoids are self‐organized, in vitro 3D structures derived from progenitor or pluripotent stem cells. During culture, these tissues secrete small extracellular vesicles (sEVs)—functional bioactive molecules—into their microenvironment. Here, we differentiated iPSC‐derived cerebral organoids (COs) under three culture conditions (static ...

Choroid plexus carcinoma in a cow [PDF]

Ciência Rural, 2009
A red, firm 3.5x3.0x3.0cm mass was found within the right lateral ventricle, compressing the hippocampus and thalamus of the brain of a 4-year-old cow. The pituitary was enlarged and firm. Histologically, both the brain and pituitary masses consisted of moderately pleomorphic epithelial cells arranged as rosettes or sheets supported by a delicate ...
