Intraspinal primitive neuroectodermal tumors (PNETs) are extremely rare and are aggressive with poor outcomes. Till date only 41 cases of intraspinal PNET have been reported. Here we report four new cases. Total excision of the tumor was done in three patients and partial excision in one patient. The unusual clinical features were vertebral metasis in one patient and short history of symptoms f...

a case of pleomorphic adenoma in sweat gland is reported here. the histopathologic report confirmed the diagnosis. pleomorphic adenoma is most common in salivary glands but very rare in sweat glands. pleomorphic adenoma in sweat gland and the similar tumors of eccring sweat gland are described that bear a striking resemblance to pleomorphic adenomas of salivary gland. upon closer examination, t...

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...

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...

A 54-year-old woman presented with intractable perianal, bilateral buttock, and radiating thigh/calf pain. An MRI scan showed an intradural, contrast-enhancing, ovoid mass in the cauda equina region at L1-L2. At laminectomy, the ovoid mass arose from a nerve root and, intact, was gross totally resected. Histologically, the dominant pattern was that of schwannoma. One year thereafter, the sympto...

•Central type primitive neuroectodermal tumor (cPNET) of the ovary is difficult to treat.•Etoposide, cisplatin and cyclophosphamide is a pediatric medulloblastoma regimen.•Our case with cPNET responded to this combination chemotherapy.

A primitive neuroectodermal tumour of the kidney is a rare malignancy. We report the computed tomographic features and the histopathological correlation of such a tumour occurring in a middle-aged man. Although the radiological appearance has significant overlap with other renal tumours, this tumour should be included in the differential diagnosis of a large renal mass in younger patients.
