Malignant neoplasm of mixed mesenchymal and neuroepithelial origin (ectomesenchymoma) of thigh
Journal of Surgical Oncology, 1984AbstractA 49‐year‐old man had a malignant soft tissue tumor of the right thigh with metastasis to the femoral region and lower quadrant of the anterior abdominal wall on the right side and the left supraclavicular lymph nodes. The neoplasm showed features of chondrosarcoma and primitive neuroectodermal tumor (combined neuroblastoma, ependymoma ...

Small‐Cell Neuroepithelial Tumor of Skin: A Merkel‐Cell Neoplasm?
The Journal of Dermatologic Surgery and Oncology, 1982Two patients with small‐cell undifferentiated neuroepithelial tumors of skin are reported. The histologic and ultrastructural features of this neoplasm are presented. Characteristic membrane‐bound, dense‐core neurosecretory granules were seen in the cytoplasm of the tumor cells in both cases.

Neuroepithelial neoplasms of childhood were examined immunohistochemically using antibodies against a neurofilament polypeptide and glial fibrillary acidic protein. Ninety-one cases, including 11 controls, were examined. Positively reacting cells, indicating neuronal and glial differentiation, were found in 59 of the 80 tumors.

Synaptophysin is an integral membrane glycoprotein with an Mr of 38,000 that occurs in the small, clear vesicles present in neuronal cells and tumors as well as in pancreatic islet cells and various neuroendocrine (NE) carcinomas. We found that synaptophysin is also expressed in normal NE cells of the lungs of newborn rabbits and mice as well as of ...

FAMILIAL OCCURRENCE OF DYSEMBRYOPLASTIC NEUROEPITHELIAL TUMOR-LIKE NEOPLASM OF THE SEPTUM PELLUCIDUM
Neurosurgery, 2008Dysembryoplastic neuroepithelial tumor (DNT)-like neoplasms of the septum pellucidum are extremely rare. In this article, we report the familial occurrence of these neoplasms.We report two cases of such neoplasms: Patient 1, a 42-year-old woman, and Patient 2, the 20-year-old nephew of Patient 1.

Abstract Four cases are described of intracranial neoplasms of mixed mesenchymal and neuroepithelial (glial) type. The multipotential mesenchyme differentiated into meningioma, neurilemmoma and rhabdomyosarcoma in various combinations, but meningioma was common to all 4 instances.

3. Dysembryoplastic neuroepithelial tumourlike neoplasm of the septum pellucidum: a case report
Pathology, 2015Background Dysembryoplastic Neuroepithelial Tumour-like Neoplasm of the Septum Pellucidum is a rare, low grade CNS neoplasm that may be misdiagnosed as a diffuse glioma. Clinical features We report a case of a 22 year old woman who presented with a first seizure.

[Radiation and combined treatment of anaplastic neuroepithelial neoplasms].
Meditsinskaia radiologiia, 1990The data on 645 patients with anaplastic neuroepithelial tumors subjected to radiotherapy, irradiation with radiosensitizers (metronidazole) and chemoradiotherapy are presented. Total-differential brain irradiation was applied: 10-40 Gy on the whole brain and 10-20 Gy on the tumor bed. Fractionation depended on tumor radiosensitivity.
