Reassessing Bone Marrow Aspirate and Trephine Biopsies in Staging for Paediatric and Young Adult Patients With Ewing Sarcoma and Rhabdomyosarcoma

Pediatric Blood &Cancer, Volume 73, Issue 10, October 2026.
ABSTRACT Ewing sarcoma (ES) and rhabdomyosarcoma (RMS) are aggressive malignancies in children and adolescents where metastases impact prognosis. 18F‐fluoro‐2‐deoxy‐d‐glucose positron emission tomography/computed tomography (FDG‐PET/CT) and bone marrow aspirate and trephine biopsies (BMAT) are used to identify disease involvement.

High-resolution array-based comparative genomic hybridization of medulloblastomas and supratentorial primitive neuroectodermal tumors

, 2006
Medulloblastomas and supratentorial primitive neuroectodermal tumors are aggressive childhood tumors. We report our findings using array comparative genomic hybridization (CGH) on a whole-genome BAC/PAC/cosmid array with a median clone separation of 0.97

Primitive Neuroectodermal Tumor of the Gallbladder

Archives of Pathology & Laboratory Medicine, 2004
Abstract Ewing sarcoma/primitive neuroectodermal tumor (ES/ PNET) most commonly occurs in the soft tissues of the extremities and the paravertebral areas. To our knowledge, no case of PNET has been reported in the gallbladder to date. We report a case of PNET of the gallbladder occurring in a 53-year-old woman.

A Rare Instance of Adult Medulloblastoma Presenting Imaging Heterogeneity Correlating With Molecular Subtypes and Anatomical Locations

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT We report an adult medulloblastoma presenting as two imaging‐distinct lesions: a uniformly enhancing torcular mass (WNT‐activated) and a non‐enhancing cerebellar tumor (SHH‐activated). A cohort analysis confirmed torcular location favors uniform enhancement, mimicking meningioma.
