Melanotic neuroectodermal tumor of infancy

Klinische Pädiatrie, 1998
A 6-month-old female presented with a swelling of the left superior maxillary bone. A radiograph revealed a radiolucent lesion in the left anterior maxilla, and CT, showed a solid mass. At surgery, the lesion was a cystic dental tumor of ectopic location which was treated by excision.

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.

Cervical Primitive Neuroectodermal Tumor

Gynecologic Oncology, 2001
Primitive neuroectodermal tumors (PNETs) are rare and potentially aggressive malignancies.A 24-year-old woman in her eighth week of pregnancy presented with a cervical mass. Tissue biopsy demonstrated poorly differentiated carcinosarcoma with neuroendocrine features. Immunohistochemical studies confirmed the diagnosis of PNET.

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 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.

Melanotic Neuroectodermal Tumor of Infancy

Otolaryngology–Head and Neck Surgery, 1987
A case of melanotic neuroectodermal tumor of infancy has been presented, and the etiology, clinical presentation, and management of this rare tumor have been discussed. The tumor may not be familiar to most otolaryngologists and should be included in the differential diagnosis of pediatric head and neck neoplasms.

Neuroradiology of primitive neuroectodermal tumors

Neuroradiology, 1983
The neuroradiological findings in four cases of primitive neuroectodermal tumor of the cerebrum are described. These highly malignant neoplasms of childhood present as large, enhancing cerebral masses with extensive neovascularity. Cerebrospinal fluid seeding is common and distant extraneural metastases may occur.

Review of spinal neuroectodermal tumor

British Journal of Neurosurgery, 2012
Primary spinal primitive neuroectodermal tumors (PNETs) are rare tumors. Most of these tumors occur in children and young adults. To date, 47 cases of primary spinal PNET have been reported in the literature. These tumors are highly aggressive with rapid growth.

Medulloblastoma and primitive neuroectodermal tumors

2012
Medulloblastomas and sPNETs remain highly problematic tumors to treat. Prognosis has improved over the past two decades, but many children who survive treatment have significant long-term sequelae. The improvements in outcome have been due to advances in surgical techniques, the wider use of chemotherapy, and the more judicious use of radiotherapy. For
