Malignant Peripheral Nerve Sheath Tumor of the Liver: A Case Report

A large, rapidly growing malignant peripheral nerve sheath tumor (MPNST) of the liver in a young female patient, not associated with von Recklinghausen’s disease, is presented. Diagnosis was based on detailed immunohistochemical and electromicroscopic examination beside the characteristic H&E picture. As far as we know, this is the first reported, unambiguously proven “de novo” MPNST in the liver. Differential diagnostic problems are discussed and a review of the literature is given.
