Primitive  neuroectodermal  tumor  (PNET)  of  kidney  is  an  extremely  rare  renal  neoplasm  with only about fifty reported cases in literature.  Presumably,of neural crest origin, these tumors behave  aggressively  and  carry  a  poor prognosis.  We  report  a  case  of  22-year  old  female  patient complaining of left loin pain with recurrent hematuria for last 3 months. On clinical ex...

Probabilistic Neural Network (PNN) also termed to be a learning machine is preliminarily used with an extension of various image classifications based on Training networks and Testing networks. To efficiently detect Brain Tumor cells, clustering method based on FCM can also be implemented. The Probabilistic Neural Network (PNN) will be employed to classify the various stages of Tumor cut levels...

Neural precursor cells contribute to adult neurogenesis and to limited attempts of brain repair after injury. Here we report that in a murine experimental glioblastoma model, endogenous neural precursors migrate from the subventricular zone toward the tumor and surround it. The association of endogenous precursors with syngenic tumor grafts was observed, after injecting red fluorescent protein-...

Current therapies for gliomas often fail to address their infiltrative nature. Conventional treatments leave behind small clusters of neoplastic cells, resulting in eventual tumor recurrence. In the present study, we have evaluated the antitumor activity of neural progenitor cells against gliomas when stereotactically injected into nucleus Caudatus of Fisher rats. We show that the rat neural pr...

Pediatric brain tumors are significant causes of morbidity and mortality. It has been hypothesized that they derive from self-renewing multipotent neural stem cells. Here, we tested whether different pediatric brain tumors, including medulloblastomas and gliomas, contain cells with properties similar to neural stem cells. We find that tumor-derived progenitors form neurospheres that can be pass...

Neuromuscular choristoma (NMC) is a rare benign tumor involving nests of myocytes and neural elements that primarily affects peripheral nerves, much less commonly can present intracranially, cranial nerves. It has previously been called hamartoma or triton tumor. Patients typically in the first two decades life with nerve palsies generalized neurologic symptoms.
