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.

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.

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.

Multiple primitive neuroectodermal tumors

Journal of the American Academy of Dermatology, 1994
Primitive neuroectodermal tumors are rare, highly aggressive neoplasms that affect both sexes and occur in all age groups. They are a large group of neoplasms with neuroepithelial differentiation, including cutaneous neuroblastomas. Histopathologically they are characterized by a rather uniform population of small, dark cells, with or without Homer ...

PRIMITIVE NEUROECTODERMAL TUMOR OF THE PROSTATE

Journal of Urology, 2003
A 27-year-old man presented with dysuria and pelvic discomfort. Physical examination revealed a palpable suprapubic mass extending above the umbilicus. Digital rectal examination demonstrated a firm pelvic mass, consistent with a locally advanced prostatic tumor. The patient had no manifestation of a paraneoplastic syndrome. Computerized tomography and

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

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.

Primitive Neuroectodermal Tumors and Ewingʼs Sarcoma

The American Journal of Surgical Pathology, 1992
Many of the major solid, malignant tumors of childhood have histologic similarities that reflect their dysembryonic and primitive features. One subset of these neoplasms, Ewing's sarcoma (ES) and primitive neuroectodermal tumor (PNET), presents primarily in the bone and soft tissues.

[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 ...
