... Ohdan Abstract Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue tumors that arise from a peripheral nerve or exhibit nerve sheath differentiation. Most of these tumors arise on the trunk, ... primarily arising from the greater omentum. To the best of our knowledge, this is the first reported case of an MPNST arising from the greater...
