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 ...

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.
