We report a 21-year-old man with a primitive neuroectodermal tumor (PNET) of the kidney that was difficult to distinguish from other small round cell tumors, e.g., small cell carcinoma, malignant lymphoma, and Wilms' tumor. Pathologically, a primitive rosette-like pattern was shown by H&E staining; expression of MIC-2 was indicated by an ...

Primitive neuroectodermal tumor of the leptomeninges

Neuroradiology, 1991
Primitive neuroectodermal tumor (PNET) without an obvious intraparenchymal mass lesion and with diffuse spread in the subarachnoid space is rare. We report such a rare case and discuss the computed tomography (CT) and magnetic resonance (MR) features.

RECTAL PRIMITIVE NEUROECTODERMAL TUMOR

Pediatric Pathology & Molecular Medicine, 2003
We report the clinical, histologic, immunohistochemical, and molecular findings of a Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET) localized to the rectum in a 17-year-old boy. Notably the 4.5 x 4 x 4-cm sessile mass was spontaneously eliminated through the anus, producing an episode of hemorrhagic shock.

Primitive Neuroectodermal Tumor of the Heart

The Annals of Thoracic Surgery, 2012
We present a case of primitive neuroectodermal tumor of the left atrium with involvement of the coronary sinus. The initial presentation was of cardiac tamponade resulting from the size of the tumor. There was no evidence of tumor elsewhere, and after complete resection and without adjuvant chemotherapy the patient is well at 2-year follow-up.

Neuroradiology of primitive neuroectodermal tumors

Neuroradiology, 1983
The neuroradiological findings in four cases of primitive neuroectodermal tumor of the cerebrum are described. These highly malignant neoplasms of childhood present as large, enhancing cerebral masses with extensive neovascularity. Cerebrospinal fluid seeding is common and distant extraneural metastases may occur.
