INTRODUCTION Peripheral primitive neuroectodermal tumor of the cervix uteri is extremely rare. Between 1987 and 2010, there were only nine cases reported in the English literature, with considerably different management policies. CASE PRESENTATION A 45-year-old Iranian woman presented to our facility with a primitive neuroectodermal tumor of the cervix uteri. Her clinical stage IB2 tumor was ...

RATIONALE Primary spinal primitive neuroectodermal tumors (PNETs) are highly malignant tumors, which are extremely rare entities and primary intramedullary PNETs are extremely rare. Till now, only 24 cases of primary intramedullary PNET have been reported. PATIENT CONCERNS A 26-year-old male presented with progressive low back and lower limb pain for 1 month. DIAGNOSES Based on MRI and hist...

Peripheral primitive neuroectodermal tumors - also known as Ewing sarcomas - are a rare type of malignant tumor the histology of which characteristically reveals the presence of small round cells. Typically, t(11;22) translocation is observed. We describe the case of a 45-year-old man with a subcutaneous peripheral primitive neuroectodermal tumor in which the t(11;22) translocation was detected...

Primitive neuroectodermal tumor is a small round cell malignancy which rarely involves the orbit. We report a case of a two-year old male child presenting as unilateral eccentric proptosis with extraconal and intraconal mass, diagnosed as primary peripheral primitive neuroectodermal tumor (pPPNET) on histopathology and immunohistochemistry. There is no defined consensus in the management of the...

INTRODUCTION Peripheral primitive neuroectodermal tumors of the urinary bladder are rare and tend to occur in an older age group than do their counterparts in bones and soft tissue. CASE PRESENTATION We report a case of peripheral primitive neuroectodermal tumor of the urinary bladder in a 67-year-old woman of Arab origin. She had undergone transurethral resection followed by chemotherapy bec...

Primitive neuroectodermal tumor (PNET) is highly malignant and extremely rare in the spine. We present a case with primary spinal primitive neuroectodermal tumor (PSPNET) which involved epidural space of thoracic spine with cord compression. Magnetic resonance imaging (MRI) showed an isointense epidural lesion on T1WI and T2WI. Heterogeneous enhancement following the administration of gadoliniu...

PURPOSE To investigate the role of proton MR spectroscopy in pediatric cerebellar tumor diagnosis. METHODS Single voxel pulse sequences with long echo time (135 or 270 milliseconds, voxel size 8 to 19 cm3), were used to obtain proton spectra of primary pediatric cerebellar tumors. Eleven primitive neuroectodermal tumors (patient age, 2 to 12 years; mean, 7 years), 11 low-grade astrocytomas (a...
