Primitive neuroectodermal tumor of the vagina

Gynecologic Oncology, 2003
Primitive neuroectodermal tumor is grouped together with Ewing sarcoma of the bone, but its presentation includes a wider age range and more central locations than its osseous counterpart. Presentation in vagina is exceedingly rare.A 34-year-old woman with personal history of kidney transplant presented with a painless vaginal mass.

Primitive neuroectodermal tumor of the kidney

Medical Molecular Morphology, 2009
We report a 21-year-old man with a primitive neuroectodermal tumor (PNET) of the kidney that was difficult to distinguish from other small round cell tumors, e.g., small cell carcinoma, malignant lymphoma, and Wilms' tumor. Pathologically, a primitive rosette-like pattern was shown by H&E staining; expression of MIC-2 was indicated by an ...

Extracranial primitive neuroectodermal tumor

Medical and Pediatric Oncology, 1984
AbstractAn 11‐year‐old white girl was admitted to The Children's Hospital of Philadelphia in July 1983 for evaluation of metastatic tumor. She had been well until July 1982, when a mass developed over the right scapula. Treatment with warm compresses and antibiotics resulted in no improvement, and incision and drainage were unproductive.

Melanotic neuroectodermal tumor of infancy

The Laryngoscope, 1978
AbstractThe lack of knowledge regarding the histogenesis of the melanotic neuroectodermal tumor of infancy may account for the numerous names given to this neoplasm. The most appropriate nomenclature is melanotic neuroectodermal tumor of infancy as this term is both clinically descriptive and reflects its most likely histogenesis.

Gastrointestinal Neuroendocrine/Neuroectodermal Tumors

Pathology Patterns Reviews, 2001
This article reviews the cause and clinical and pathologic features of gastrointestinal carcinoid tumors and small cell carcinomas. Their pathogenesis and molecular features are reviewed. Tumor arrays within a given site, as in the stomach, are compared with one another to highlight their histologic features and differing biologies.

Primitive neuroectodermal tumor of the leptomeninges

Neuroradiology, 1991
Primitive neuroectodermal tumor (PNET) without an obvious intraparenchymal mass lesion and with diffuse spread in the subarachnoid space is rare. We report such a rare case and discuss the computed tomography (CT) and magnetic resonance (MR) features.

RECTAL PRIMITIVE NEUROECTODERMAL TUMOR

Pediatric Pathology & Molecular Medicine, 2003
We report the clinical, histologic, immunohistochemical, and molecular findings of a Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET) localized to the rectum in a 17-year-old boy. Notably the 4.5 x 4 x 4-cm sessile mass was spontaneously eliminated through the anus, producing an episode of hemorrhagic shock.

Melanotic Neuroectodermal Tumor of Infancy

Southern Medical Journal, 1988
We have presented the only melanotic neuroectodermal tumor of infancy treated at the Children's Hospital of Alabama in the last seven years. Early diagnosis, relatively aggressive surgical treatment, and a team approach to the patient's management and rehabilitation should provide an excellent cure rate and near normal development of the patient ...

Neuroectodermal tumor and monoclonal antibodies

Journal of Pediatric Hematology/Oncology, 1984
Antibody-producing clones were obtained by hybridization of spleen cells from mice immunized with whole cultured human tumor cells and mouse myeloma cells, P3UX59AG8. The tumor cells were derived from a peripheral primitive neuroectodermal tumor. One of the antibodies produced by these clones reacts with the original cell line, SK-PN-DW, and other more
