H3F3A-G34R mutant high grade neuroepithelial neoplasms with glial and dysplastic ganglion cell components [PDF]

Acta Neuropathologica Communications, 2019
The recently described malignant neuro-epithelial tumors with histone H3F3A point mutations at G34 (NET-H3-G34) occur most often in cerebral hemispheres of teenagers and young adults, and have a generally adverse prognosis.

Suprasellar Desmoplastic Infantile Ganglioglioma in a 7‐Month‐Old Infant: A Rare Diagnostic Consideration in Infant Suprasellar Masses [PDF]

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Desmoplastic infantile ganglioglioma should be considered when an infant presents with a suprasellar mass, nystagmus, and developmental delay. Deep midline location limits resection, so BRAF V600E testing matters: it can open a targeted treatment option when surgery cannot control the disease.

Discrepancies in diagnoses of neuroepithelial neoplasms [PDF]

Cancer, 2000
Valid and reliable diagnoses of disease are key both to meaningful epidemiologic and clinical investigations and to decision-making about appropriate treatment. One previous study highlighted the lack of precision in diagnosing primary brain tumors in a neuropathology referral practice.

Pigmented olfactory neuroblastoma. A new example of melanotic neuroepithelial neoplasm [PDF]

Cancer, 1982
The light and electron microscopic features of a pigmented olfactory neuroblastoma are described. The neuroblastic nature of the tumor was confirmed by the demonstration of axons, some of which originated from the neoplastic cells, and by the presence of dense-core vesicles in the perikarya and processes of the tumor cells.

INSM1: A Novel Immunohistochemical and Molecular Marker for Neuroendocrine and Neuroepithelial Neoplasms [PDF]

American Journal of Clinical Pathology, 2015
Neuroendocrine neoplasms (NENs) are heterogeneous neoplasms, which are sometimes malignant, although predicting metastasis is difficult. INSM1 is a transcription factor expressed transiently in embryonic neuroendocrine (NE) tissue, thought to coordinate termination of cell division with differentiation of NE and neuroepithelial cells. In adult tissues,

PPARs in Human Neuroepithelial Tumors: PPAR Ligands as Anticancer Therapies for the Most Common Human Neuroepithelial Tumors

PPAR Research, 2010
Neuroepithelial tumors represent a heterogeneous class of human tumors including benignant and malignant tumors. The incidence of central nervous system neoplasms ranges from 3.8 to 5.1 cases per 100,000 in the population. Among malignant neuroepithelial

Neoplasm of mixed mesenchymal and neuroepithelial origin of the optic nerve. [PDF]

British Journal of Ophthalmology, 1977
A case is reported of a 19-year-old male having right proptosis for 4 years because of a mixed meningioma and astrocytoma of the ipsilateral optic nerve. The sheath of this nerve is analogous to the leptomeninges, and neuroglial cells constitute the stroma of the nerve.
