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...

متن کاملMalignant 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: Differentiation Patterns and Immunohistochemical Features - A Mini-Review and Our New Findings
Malignant peripheral nerve sheath tumors (MPNST) represent a group of highly heterogeneous human malignancies often with multiple histological origins, divergent differentiation patterns, and diverse immunohistochemical presentations. The differential diagnosis of MPNST from other spindle cell neoplasms poses great challenges for pathologists. This report provides a mini-review of these unique ...
