Malignant Peripheral Nerve Sheath Tumors (MPNST)
INTRODUCTION Malignant peripheral nerve sheath tumors (MPNSTs) are sarcomas which originate from peripheral nerves or from cells associated with the nerve sheath, such as Schwann cells, perineural cells, or fibroblasts. Because MPNSTs can arise from multiple cell types, the overall appearance can vary greatly from one case to the next. This can make diagnosis and classification somewhat difficu...
متن کاملMalignant peripheral nerve sheath tumors (MPNST) in NF1-affected children.
BACKGROUND Malignant peripheral nerve sheath tumors (MPNST) constitute a heterogeneous group of malignant tumors that probably arise from cells of the peripheral nerve sheath. Association of MPNST with neurofibromatosis type 1 (NF1) is frequently reported. MPNST contribute significantly to the reduced life-span of NF1-patients. At present there are only sparse data on MPNST in NF1-children. The...

Malignant peripheral nerve sheath tumours (MPNSTs) may occur in any peripheral nerve. They are often found in the chest wall and the posterior mediastinum. On the other hand, primary pulmonary MPNST is extremely rare, and surgically treated cases have been reported.

متن کاملMalignant peripheral nerve sheath tumour (malignant epithelioid Schwannoma) of the parotid gland.
PROBLEMS/OBJECTIVES Malignant peripheral nerve sheath tumours are uncommon soft tissue tumours originating from Schwann cells or nerve sheath cells. Malignant epithelioid schwannoma is an aggressive variant of malignant peripheral nerve sheath tumour, and unfortunately is related with a high rate of recurrence and poor prognosis. METHODOLOGY In this study we present a rare case of malignant e...
متن کاملMalignant peripheral nerve sheath tumour of maxilla.

This tumour is usually found in lower extremities and only 10-12% occur in head and neck region. The diagnosis is considered as the most elusive and difficult among soft tissue sarcomas because of its non specific presentation, both clinically as well as ...
