Primitive neuroectodermal tumor of the kidney

Medical Molecular Morphology, 2009
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 uterus

Gynecologic Oncology, 2007
: Primitive peripheral neuroectodermal tumors (PNETs) of the uterus are rare. Recent data have demonstrated improved response rates with adjuvant chemotherapy.: A 26-year-old, gravida 2, para 1, Filipina female underwent an emergent cesarean section for fetal indications.

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.

Extracranial primitive neuroectodermal tumor

Medical and Pediatric Oncology, 1984
AbstractAn 11‐year‐old white girl was admitted to The Children's Hospital of Philadelphia in July 1983 for evaluation of metastatic tumor. She had been well until July 1982, when a mass developed over the right scapula. Treatment with warm compresses and antibiotics resulted in no improvement, and incision and drainage were unproductive.

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.

Multiple primitive neuroectodermal tumors

Journal of the American Academy of Dermatology, 1994
Primitive neuroectodermal tumors are rare, highly aggressive neoplasms that affect both sexes and occur in all age groups. They are a large group of neoplasms with neuroepithelial differentiation, including cutaneous neuroblastomas. Histopathologically they are characterized by a rather uniform population of small, dark cells, with or without Homer ...

Primitive neuroectodermal tumors/medulloblastoma

Current Neurology and Neuroscience Reports, 2002
The therapy for medulloblastoma/primitive neuroectodermal tumors of the central nervous system is surgery, followed by combination chemo-radiotherapy. The radiation field is the entire craniospinal axis, which is only avoided when treating infants. The treatment is, therefore, lengthy and toxic.

Primitive Neuroectodermal Tumors and Ewingʼs Sarcoma

The American Journal of Surgical Pathology, 1992
Many of the major solid, malignant tumors of childhood have histologic similarities that reflect their dysembryonic and primitive features. One subset of these neoplasms, Ewing's sarcoma (ES) and primitive neuroectodermal tumor (PNET), presents primarily in the bone and soft tissues.
