High-Resolution Array-Based Comparative Genomic Hybridization of Medulloblastomas and Supratentorial Primitive Neuroectodermal Tumors

open access: yesJournal of Neuropathology and Experimental Neurology, 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

The neuroectodermal tumor of bone

The American Journal of Surgical Pathology, 1984
Four small round cell malignant tumors of bone occurring in children are described. There was no catecholamine secretion and the clinical, radiologic, and biopsy diagnosis in each was Ewing's sarcoma. Glycogen was sparse both on imprints and in tissue sections. The tumors, when extensively sampled, had areas of a lobular growth pattern and Homer Wright

Primitive neuroectodermal tumors

Critical Reviews in Neurosurgery, 1998
The primitive neuroectodermal tumors (PNETs) of Hart and Earle constitute an important fraction of pediatric brain tumors that are clinically characterized by their aggressive behavior. In 1983, Rorke expanded the term "PNET" to include all small cell embryonal neoplasms of neuroectodermal origin, regardless of the location of the tumor. More recently,

Melanotic neuroectodermal tumor in a newborn

International Journal of Pediatric Otorhinolaryngology, 2005
Melanotic neuroectodermal tumor of infancy (MNTI) is an uncommon, fast-growing, pigmented neoplasm of neural crest origin; it primarily affects the maxilla of the infants during the first year of life. Approximately 200 instances of this tumor are reported in the medical literature.

Malignant sympathetic neuroectodermal tumor

The American Journal of Surgery, 1953
Abstract A case of malignant sympathetic neuroectodermal derivative tumor is presented and the following features are discussed. 1. 1. Early in the patient's course on the basis of an initial positive interpretation of the bichromate reaction and the histologic picture a diagnosis of benign paraganglioma was made.

Primitive Neuroectodermal Tumor of the Orbit

Ophthalmic Plastic & Reconstructive Surgery, 1994
A 10-year-old girl developed a lump in the lateral aspect of the right eyebrow over a 3-week period. Computed tomography and magnetic resonance imaging revealed a soft-tissue mass in the superolateral aspect of the right orbit associated with zygo-maticofrontal bone erosion and hyperostosis.
