MPNST
Also written as: MPNST — Malignant Peripheral Nerve Sheath Tumour
Acronym for Malignant Peripheral Nerve Sheath Tumour, a high-grade sarcoma arising from peripheral nerve tissue, occasionally encountered in the maxillofacial region.
Full Definition
MPNST is the internationally accepted abbreviation for malignant peripheral nerve sheath tumour and is widely used in pathology reports, oncology literature, and multidisciplinary team documentation. In the oral and maxillofacial context, its use requires particular care as the tumour is rare and may be confused with other spindle cell neoplasms. Editors should ensure the abbreviation is defined in full at first use and should alert authors to the availability of more specific terminology when NF1 association or radiation induction is relevant. MPNST carries a poor prognosis and its accurate identification in pathology documents has direct clinical implications.
Usage
Usage note: Always define at first use. Confirm whether NF1 association or radiation aetiology should be specified in the document context.
