The primitive neuroectodermal tumor (PNET) belongs to a group of highly malignant tumors and is composed of small round cells of a neuroectodermal origin. Categorized in the same tumor family as Ewing sarcoma, the PNET is most likely to occur in bones and soft tissues. However, a small number of PNET cases arising in the pelvis have been reported as well. We present three cases of pelvic PNET: ...

BACKGROUND Non-functioning (NF) pancreatic neuroendocrine tumors (pNET) often have an indolent outcome. A consensus to submit patients with large (>2 cm) NF-pNET to surgery already exists; but a conservative approach for small (≤2 cm) NF neoplasms has been proposed. AIM To identify prognostic factors for survival and progression free survival (PFS) of NF-pNET, evaluating whether surgery may b...

Peripheral primitive neuroectodermal tumor now termed as Ewings sarcoma/PNET, representing a family of tumors with varying degrees neuronal differentiation and genetic rearrangements. Most common sites are extraosseous involving trunk lower limb. Base tongue is very rare site for Ewing’s/PNET, hence in view rarity the location an uncommon presentation, case has been reported better understandin...

Complete surgical resection remains the only curative treatment option for pancreatic neuroendocrine tumor (PNET). However, the proper management of PNET with liver metastasis remains debatable. We describe two patients with PNET and multiple liver metastases that were treated with aggressive surgical resection. In one case, a 45-year-old man with non-functional PNET with unresectable liver met...

Primitive neuroectodermaltumor (PNET), which belongs to the Ewing’s sarcoma (ES) family of tumors, is mainly seen in children and young adults. PNETs are extremely rare in the maxilla. Here, we report a case of a 15y old female diagnosed with PNET of maxilla following detailed radiologic,histopathologic, immunohistochemicalstudies. Though the imaging features of PNET are non-specific and defini...

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 ...

Primitive neuroectodermal tumors (PNET) of the brain include medulloblastoma (MB) and central nervous system primitive neuroectodermal tumor (CNS PNET) subtypes, which share histological features yet differ at the genomic level and in clinical outcome. Delineation of the genetic anomalies between PNET subtypes is a current challenge for establishing effective targeted therapeutic strategies aga...

BACKGROUND Medulloblastoma and primitive neuroectodermal tumours (PNET) are the most common central nervous system (CNS) embryonal tumours diagnosed in childhood. Survival outcomes are worse for children diagnosed with CNS PNET compared to medulloblastoma. Less is known about survival outcomes in teenagers and young adults (TYA). METHODS Data were extracted from two population-based cancer re...
