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.

Primitive neuroectodermal tumor of the uterus

Gynecologic Oncology, 2007
: Primitive peripheral neuroectodermal tumors (PNETs) of the uterus are rare. Recent data have demonstrated improved response rates with adjuvant chemotherapy.: A 26-year-old, gravida 2, para 1, Filipina female underwent an emergent cesarean section for fetal indications.

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

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 ...

Primitive Neuroectodermal Tumor of the Heart

The Annals of Thoracic Surgery, 2012
We present a case of primitive neuroectodermal tumor of the left atrium with involvement of the coronary sinus. The initial presentation was of cardiac tamponade resulting from the size of the tumor. There was no evidence of tumor elsewhere, and after complete resection and without adjuvant chemotherapy the patient is well at 2-year follow-up.

Melanotic Neuroectodermal Tumor of Infancy

Journal of Craniofacial Surgery
Background: Melanotic neuroectodermal tumor of infancy (MNTI) is a rare, benign but locally aggressive neoplasm of neural crest origin, typically arising in the anterior maxilla of infants under 1 year of age. Clinically, it often mimics an eruption cyst, leading to potential diagnostic delay.

Melanotic neuroectodermal tumor of infancy

Journal of Oral and Maxillofacial Surgery, 1996
Melanotic neuroectodermal tumor of infancy (MNTI) is an unconunon, almost invariably benign neural crest origin neoplasm that was first described in 1918 by Krompecher. 1-5 As the name implies, it is found predominantly in infancy ; 82% of patients are 6 months of age or younger, and 92% are younger than 12 months.
