mandibular primitive neuroectodermal tumor in an adult dog
Authors
abstract
this is the report of a mandibular neuroectodermal/ewing sarcoma in an 8-year-old male cross breed dogthat is unique because of tumor origin location. pedunculated, ulcerative, firm 6.0 × 4.0 × 5.5 cm tumor masseffaced the bone at the rostral part of the mandible and had a white-sanguineous color at cross sectionappearance. histopathologically, small round blue cell tumor was diagnosed. immunohistochemically, tumorcells were positive for vimentin, s100 and glial fibrillary acidic protein (gfap) and negative for neuronspecific enolase (nse) and desmin. mandibular location is a rare event in these types of tumors.

RATIONALE Central nervous system primitive neuroectodermal tumors (CNS PNETs) mostly occur in children and present as cerebellar medulloblastoma. A few cases of PNETs occur in the cerebral hemisphere. The presence of a PNET in ventricles is extremely rare. The prognosis of CNS PNET is extremely poor, and the 5-year survival rate does not exceed 35%. In the present study, we describe the first c...

The primitive neuroectodermal tumor (PNET) belongs to a group of highly malignant tumors and is composed of small round cells of a neuroectodermal origin. Categorized in the same tumor family as Ewing sarcoma, the PNET is most likely to occur in bones and soft tissues. However, a small number of PNET cases arising in the pelvis have been reported as well. We present three cases of pelvic PNET: ...

Primitive neuroectodermal tumor (PENETs) is an uncommon malignancy of bone and soft tissue witch rarely occurs in the kidney. In more than 90% of the cases, the tumor cells relieves a balanced translocation (11; 22) (q24; q12). Immunohistochemical staining may be required for diagnosis of PENET. The cells of tumor express CD99, vimentin, NSE, FL1 but do not express Ck, LCA, myogenin, and WT1. W...

Primitive neuroectodermal tumor (PNET) is anundifferentiated neoplasm arising from the germinal matrix of the primitive neural tube. It is predominantly an infratentorial tumor of childhood. Adult supratentorial PNETs are less common and extraneural metastasis are extremely unusual. Only five sporadic cases were reported in the international literature.1–6 In this article, we report a rare case...
