Peripheral Primitive Neuroectodermal Tumor - PNET

Acta chirurgiae orthopaedicae et traumatologiae Cechoslovaca, 2006
The authors describe three cases of peripheral primitive neuroectodermal tumor. The tumor was found in soft tissues of the crus, shoulder girdle and perineum, and was also located paravertebrally and epidurally at the level of L1-L2 vertebrae. Radiological findings were not specific for this disease. The results of imaging methods (sonography, CT, MRI,

[Primitive neuroectodermal tumor].

Der Chirurg; Zeitschrift fur alle Gebiete der operativen Medizen, 1997
The primitive neuroectodermal tumor is a rare soft tissue neoplasm occurring in children and young adults. It derives from a carcinogeneic alteration of pluripotent neural crest cells, caused by a balanced reciprocal translocation t(11;22) (q24;q12). Treatment of this undifferentiated, extremely malignant small cell tumor is carried out in compliance ...

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.
