Timing of Smarcb1 and Nf2 inactivation determines schwannoma versus rhabdoid tumor development

Nature Communications, 2017
Germline mutations of the SMARCB1 gene predispose to two distinct tumor syndromes: rhabdoid tumor predisposition syndrome, with malignant pediatric tumors mostly developing in brain and kidney, and familial schwannomatosis, with adulthood benign tumors ...

Molecular heterogeneity and prognostic biomarkers in primary meningeal melanocytic tumors

Brain Pathology, EarlyView.
Integrated molecular profiling reveals biological heterogeneity among primary meningeal melanocytic tumors, identifying intermediate‐grade PMMT subgroups with distinct recurrence risk. Molecular alterations including SF3B1 mutations and chromosome 8q gains support prognostic stratification, while PRKAR1A alterations and chromosome 17/21q losses aid ...

Gliomas with pleomorphic and pseudopapillary features (GPAP) are circumscribed tumors with targetable mutations, prolonged survival, and frequent tumor predisposition

Brain Pathology, EarlyView.
DNA methylation profiling identifies GPAP as a distinct circumscribed glioma with a characteristic expansive, multicystic radiological appearance, pleomorphic and pseudopapillary histology, a recognizable CNV profile, druggable molecular alterations, and recurrent cancer predisposition syndromes.

Angiosarcoma arising in a vagal schwannoma - Report and literature review [PDF]

Schwannoma and angiosarcoma are rare occurrences. Angiosarcoma\u27s occurrence in a preexisting schwannoma is a very rare event with only fifteen cases reported in the literature. We report the sixteenth case of angiosarcoma arising in a schwannoma, a 30-

Schwannoma of the hypoglossal nerve: Review of the literature based on an illustrative case.

Molecular and clinical oncology, 2017
Schwannomas are benign tumours that originate from the myelin sheath of peripheral nerves. They are characterised by a slow growth tendency. Benign schwannomas represent 35% of the head and neck district tumours. Hypoglossal schwannomas account for 5% of
