Surgical Neurology, 1993
Supratentorial embryonal neuroepithelial tumors are undifferentiated neoplasms. We have used this term in preference to the controversial classification primitive neuroectodermal tumors (PNET). These lesions in children are malignant neoplasms which are usually fatal within 2 years of diagnosis in spite of therapy with surgery, radiotherapy, and ...

The authors report a series of 10 low-grade neoplasms arising in the midline anteriorly in the region of the septum pellucidum with many of the histologic features of dysembryoplastic neuroepithelial tumor (DNT). The patients (five female, five male) ranged in age from 6 to 35 years (mean age, 21.5 years).

Dysembryoplastic neuroepithelial tumor (DNT)-like neoplasms of the septum pellucidum are extremely rare. We reviewed 2 cases of DNT-like neoplasm of the septum pellucidum and specifically studied the immunohistochemical features and chromosomes 1p and 19q deletions. One case was a 26-year-old woman who complained of aggravated headache for 2 weeks. The

Human Pathology, 2012
Diffuse growth of gliomas is based on enhanced cell migration and remodeling of the extracellular matrix. Up-regulation of matrix metalloproteinases in gliomas is associated with a poor prognosis. The activated leukocyte adhesion molecule is considered to be indispensable for conversion of matrix metalloproteinase 2 into its active form.

Dysembryoplastic neuroepithelial tumor (DNT)- like lesions arise in extracortical locations and behave in a benign fashion similar to that of cortical DNTs. They usually come to attention by symptoms and signs of increased intracranial pressure rather than focal neurological impairment.

Cathepsin D in some neuroepithelial brain neoplasms
2004U ovom radu istraživala se uz aktivnost katepsina D u najčešćim primarnim novotvorinama SŽS-a i njegova eventualna prognostička vrijednost. U istraživanju koristila se samo imunohistokemijska metoda, te je bilo uključeno 65 humanih primarnih novotvorina SŽS-a, od toga 50 glijalnih novotvorina (10 astrocitoma - SZO stupanj II, 15 anaplastičnih ...
