Metastatic epithelioid malignant peripheral nerve sheath tumor in a known case of neurofibromatosis-1, cytomorphological appearance, and critical analysis of immunohistochemistry
Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue tumors Rolling Machines commonly arising from nerve roots in the extremities with a predilection in neurofibromatosis (NF) patients.MPNSTs are known to behave aggressively, with worse prognosis in nonresectable cases, and a 5-year survival of about 52% and 15% in resectable and
