Malignant peripheral nerve sheath tumours (MPNST) are a group of malignant tumours that arise from cells that are differentiating or have differentiated toward those of the peripheral nerve sheath.1 The heterogeneity of these cellular components and stages of differentiation have historically lead to difficulty in defining the diagnosis and behaviour of these lesions, with terms such as maligna...
متن کاملMalignant Peripheral Nerve Sheath Tumour Arising From Solitary Sclerotic Neurofibroma.
Neurofibroma is a benign neoplasm of the peripheral nerve, which occurs as multiple tumours in neurofibromatosis type 1 (NF1) or as a solitary tumour with no association with NF1. Malignant change is sometimes reported in neurofibroma in NF1, but there are few reports of malignant transformation of solitary neurofibroma. We report here a case of malignant change in a solitary sclerotic neurofib...
