neuroectodermal tumors primitive/vomiting

We reported a rare case of supratentorial primitive neuroectodermal tumors (sPNET) and reviewed the literature. A 15-year-old girl presented with a one-month history of headache and vomiting. CT scans showed a huge, solid and cystic tumor with calcification, occupying the left anterior cranial

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

A primary Ewing's sarcoma arising in the skull is relatively rare. Although a small number of case reports noted elevated carcinoembryonic antigen (CEA) in patients with primary central nervous system (CNS) neoplasms, there is no report of Ewing's sarcoma/peripheral primitive neuroectodermal tumor

A 44-year-old man discovered a swollen right testis more than 4 years earlier. He was brought to our hospital because of abdominal pain and vomiting. Enhanced computed tomography (CT) showed a swollen right testis, lung nodules, and swollen retroperitoneal and mediastinal lymph nodes. The swollen

Medulloepithelioma is a rare and highly malignant primitive neuroectodermal tumor that usually occurs in childhood. The diagnosis of this entity required only morphological analysis until the World Health Organization classification of central nervous system (CNS) tumors was revised, and now genetic

Medulloepithelioma is an extremely rare PNET in late adolescence and adults with only two cases noted in literature. These are WHO grade IV tumors with dismal prognosis. Only few cases survived beyond 5 months. We report a rare case of supratentorial medulloepithelioma in a 17 year old girl. She had

Embryonal tumors are a group of malignant neoplasms that most commonly affect the pediatric population. Embryonal tumor with abundant neuropil and true rosettes is a recently recognized rare tumor. It is composed of neurocytes and undifferentiated neuroepithelial cells arranged in clusters, cords

BACKGROUND Supratentorial primitive neuroectodermal tumors predominantly occur in children, and are rare in the adult population. Less than 100 cases of supratentorial primitive neuroectodermal tumor have been reported in adults internationally. Our case study reports this rare incident. METHODS A

The authors report the case of a peripheral primitive neuroectodermal tumor (PNET) arising in the tentorium in a 5-year-old boy who presented with frequent vomiting and mild palsy of the left abducent nerve. Following complete surgical excision of the tumor via a transpetrosal approach, the patient

An 8-year-old boy presented with a rare cerebral medulloepithelioma manifesting as headache, nausea, and vomiting. Neuroimaging demonstrated a mass containing a cyst in the left frontal lobe. Gross total resection of the tumor with a 1-cm margin was performed under intraoperative monitoring. The

Medulloepitheliomas (WHO grade IV) are rare, malignant embryonal tumors of pediatric population, classified under the central nervous system (CNS) primitive neuroectodermal tumors (PNET). Histologically, these tumors are characterized by neoplastic neuroepithelium recapitulating the embryonic neural

BACKGROUND We report on a very rare case of a supratentorial primitive neuroectodermal tumor in an adult, which presented with intracerebral hemorrhage, and review the relevant medical literature. METHODS A 42-year-old Caucasian man complained of a sudden headache and nausea-vomiting. The patient

A 7-year-old boy was admitted to our hospital because of headache and frequent vomiting. The patient was noted to have papilloedema and mild palsy of the right abducent nerve. Magnetic resonance image (MRI) revealed a large tumor in the frontal base with tumoral hemorrhage. Angiography showed the

One hundred ninety-eight children were entered on POG 8633, "Prolonged Postoperative Chemotherapy and Delayed Radiation for Children <3 years of age with Malignant Brain Tumors" (1986-1990). Thirteen manifested supratentorial nonpineoblastoma primitive neuroectodermal tumors, making this the second

Primitive neuroectodermal tumor (PNET) is a malignant small round cell tumor and typically arises from bone or soft tissue in adolescents and young adults. Renal PNET is extraordinarily rare and exhibits highly aggressive biological behavior with poor prognosis.We present here a new case of renal
