Giant malignant peripheral nerve sheath tumor of the scalp.

PURPOSE Malignant peripheral nerve sheath tumors (MPNST) constitute a group of soft tissue neoplasms with neurogenic origin. Association of MPNST with neurofibromatosis type 1 (NF1) has been frequently reported as a result of malignant transformation of a pre-existing plexiform neurofibroma. However, most of the cases are small and few have been described with giant dimensions. We describe a ca...

Intrathoracic Malignant Peripheral Nerve Sheath Tumor: Histopathological and Immunohistochemical Features

Malignant peripheral nerve sheath tumor (MPNST) is a rare nerve sheath tumor derived from Schwann cells or pleuripotent cells of neural crest. Neurogenic tumors make about 10-20% of all mediastinal tumors. Incidence of MPNST is 0.001% in general population and 0.16% in patients with neurofibromatosis I (NF I). We report a case of 60 year female presenting with progressive cough and breathlessne...

Giant Malignant Peripheral Nerve Sheath Tumor of Scalp in Non-neurofibromatosis Person: A Rare Case Report

Malignant peripheral nerve sheath tumors (MPNSTs) are rare neoplasms with an incidence of about 0.001% in general population. They usually arise from components of nerve sheath such as perineural fibroblasts or Schwann cells, and are often considered as a form of soft tissue sarcoma.1 Most of these MPNSTs are located in the buttocks, thighs, brachial plexus, and paraspinal region, and are rarel...

Malignant Peripheral Nerve Sheath Tumor in the Maxilla: Report of a Rare Case

Malignant peripheral nerve sheath tumor (MPNST) is a rare malignant tumor that develops either from a preexisting neurofibroma or de novo. The cell of origin is believed to be the Schwann cell and possibly other nerve sheath cells. In this report, we describe a rare case of MPNST that arise from the socket of second left maxillary molar that has been already extracted in a young man. He was ref...

Malignant peripheral nerve sheath tumour of scalp with extradural extension: case report.

Malignant peripheral nerve sheath tumours are uncommon aggressive soft tissue sarcomas that originate from peripheral nerves or cells associated with the nerve sheath. Scalp malignant peripheral nerve sheath tumours are extremely rare and the role of multimodality management is unclear. We report a 43-year-old female with scalp swelling and rapid growth. Imaging demonstrated an ...
