Plexiform Neurofibromas Overview

Plexiform neurofibromas (PNs) are complex, diffuse peripheral nerve sheath tumours arising from multiple nerve fascicles, occurring almost exclusively in the context of neurofibromatosis type 1 (NF1) — caused by autosomal dominant loss-of-function mutations in the NF1 tumour suppressor gene encoding neurofibromin, a RAS-GAP protein — resulting in constitutive RAS-MAPK pathway activation driving Schwann cell proliferation and tumour formation. Present from birth in the majority of affected individuals, PNs are characterised by their infiltrative growth along nerve plexuses, rendering complete surgical resection impossible in most cases and conferring lifelong risk of transformation into malignant peripheral nerve sheath tumours — a feared complication occurring in approximately 8-15% of NF1 patients and carrying poor prognosis. Patients present with disfiguring soft tissue masses, compressive neuropathy, pain, motor deficits, and functional impairment varying with tumour location — paraspinal, craniofacial, and limb PNs each presenting distinct management challenges. Diagnosis is predominantly clinical and radiological — whole-body MRI delineating tumour volume and internal target volume — within established NF1 diagnostic criteria. Selumetinib, a MEK1/2 inhibitor, represents a landmark approved therapy demonstrating meaningful and durable PN volume reduction and functional improvement, fundamentally transforming the therapeutic landscape beyond surgical debulking. Regular MRI surveillance monitoring for rapid volume increase — a malignant transformation signal — alongside pain management, physiotherapy, and ophthalmological monitoring are essential. Prognosis varies with tumour burden and malignant transformation risk; multidisciplinary NF1 specialist care, genetic counselling, and psychosocial support are integral to patient-centred long-term management.
