Melanotic neuroectodermal tumor of infancy

Oral Surgery, Oral Medicine, Oral Pathology, 1990
The case of a 2-month-old male infant treated for melanotic neuroectodermal tumor of infancy is presented to demonstrate the importance of early treatment in the containment of the growth of such lesions. Although the lesion itself is rare, the posterior maxillary location and involvement of the optic nerve in this patient's lesion made his case even ...

Melanotic Neuroectodermal Tumor of Infancy

Pediatric Dermatology, 2011
Abstract:  Melanotic neuroectodermal tumor of infancy (MNTI) is an uncommon lesion with remarkably consistent histopathologic features that arises primarily in the pediatric population. We describe a MNTI arising in the anterior maxilla of a 6‐month‐old boy.

Melanotic Neuroectodermal Tumor of Infancy

Pediatric Pathology, 1985
Melanotic neuroectodermal tumor of infancy is a specific but unusual tumor of infancy for which only sporadic cases have been reported in the literature. This paper presents a case in an infrequent site, the epididymis, and summarizes the literature on the subject.

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.

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 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.
