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.

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.

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.

Primitive neuroectodermal tumors/medulloblastoma

Current Neurology and Neuroscience Reports, 2002
The therapy for medulloblastoma/primitive neuroectodermal tumors of the central nervous system is surgery, followed by combination chemo-radiotherapy. The radiation field is the entire craniospinal axis, which is only avoided when treating infants. The treatment is, therefore, lengthy and toxic.

Primary Leptomeningeal Primitive Neuroectodermal Tumor

Journal of Neuro-Oncology, 2003
Leptomeningeal metastases are a common complication of medulloblastomas and other primitive neuroectodermal tumors (PNETs). Much rarer are PNETs apparently arising in the leptomeninges. An 8-year-old boy presented with headache and vomiting, due to neoplastic meningitis from primary neuroectodermal tumor without an identifying mass.

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.

Peripheral Primitive Neuroectodermal Tumor - PNET

Acta chirurgiae orthopaedicae et traumatologiae Cechoslovaca, 2006
The authors describe three cases of peripheral primitive neuroectodermal tumor. The tumor was found in soft tissues of the crus, shoulder girdle and perineum, and was also located paravertebrally and epidurally at the level of L1-L2 vertebrae. Radiological findings were not specific for this disease. The results of imaging methods (sonography, CT, MRI,

[Primitive neuroectodermal tumor].

Der Chirurg; Zeitschrift fur alle Gebiete der operativen Medizen, 1997
The primitive neuroectodermal tumor is a rare soft tissue neoplasm occurring in children and young adults. It derives from a carcinogeneic alteration of pluripotent neural crest cells, caused by a balanced reciprocal translocation t(11;22) (q24;q12). Treatment of this undifferentiated, extremely malignant small cell tumor is carried out in compliance ...
