INTRODUCTION 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. CASE PRESENTATION A 42-year-old Caucasian man complained of a sudden headache and nausea-vomiting. The patient rapidly deteriorated to coma. An emergency computed tomography scan showed an extensi...

UNLABELLED INTRODUCTION 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. CASE PRESENTATION A 22-year-old Hispanic man presented with headaches, blurry vision, dipl...

This is the report of a mandibular neuroectodermal/ewing sarcoma in an 8-year-old male cross breed dogthat is unique because of tumor origin location. Pedunculated, ulcerative, firm 6.0 × 4.0 × 5.5 cm tumor masseffaced the bone at the rostral part of the mandible and had a white-sanguineous color at cross sectionappearance. Histopathologically, small round blue cell tumor was diagnosed. Immunoh...

primitive neuroectodermal tumor (pnet) is usually an aggressive, rapidly progressing and metastasizing tumor. occurrence of this type of tumor in the kidney is considered as unusual and few cases have been reported so far. we present a metastatic pnet arising probably from the kidney in a 17-year-old female patient with local invasion and metastasis to the stomach. pnet should be considered as ...

OBJECTIVES: To characterize primitive neuroectodermal tumor of the kidney as a differential diagnosis for Wilms tumor, and to emphasize the severity of the disease. METHODS: We report the case of a patient with a diagnosis of primitive neuroectodermal tumor of the kidney who underwent nephrectomy and complete tumor resection combined with chemotherapy. RESULTS: Initially, the response of the pa...

The loss of genetic material from specific chromosomal locations has been identified for a number of pediatric tumors. This loss has been taken as evidence for the importance of tumor suppressor genes at these loci in the genesis of these tumors. One of these pediatric tumors, the primitive neuroectodermal tumor of the central nervous system, has not been well studied. In this report, an analys...
