Treatment of a Malignant Peripheral Nerve Sheath Tumor

Onkologie, 2009
Malignant peripheral nerve sheath tumors (MPNST) are defined as any malignant tumor deriving from or differentiating into cells of the peripheral nerve sheaths, with a high risk of local recurrence and distant metastasis. Despite aggressive surgery and adjuvant therapy, the prognosis of MPNST is poor with reported 5-year survival rates of about 50%.We ...

Metastatic Malignant Peripheral Nerve Sheath Tumor in a Newborn

Journal of Pediatric Hematology/Oncology, 2008
Malignant peripheral nerve sheath tumors are rare tumors, especially in the newborn period. Diagnosis is based on clinical findings, radiography, and fine needle biopsy or tissue sampling. Ideal management is controversial and extremely difficult. The survival rate is extremely low. We present a case of a newborn in which this tumor is diagnosed in the

Malignant neoplasms arising in association with peripheral nerves and resembling elements of the peripheral nerve are considered in this category. These tumors may arise in the setting of neurofibromatosis or may be seen sporadically in children. The unequivocal recognition of a high grade sarcoma as malignant peripheral nerve sheath tumor (MPNST ...
