Malignant Transformation of the Plexiform Neurofibroma in a Neurofibromatosis Type 1 Patient-A Case Report and Literatures Review

We present a case of Von-Recklinghausen disease with malignant transformation of a plexiform neurofibroma over her left leg. The proposita is a 35-year-old female with typical clinical features of neurofibromatosis type 1 (NF1) including cafe-au-lait spots, Lisch nodule and multiple fibromas. The major problem is a rapid growing mass within her left calf and ankle with resultant limb deformation, walking difficulties and debilitating pain. Besides that, there exists the great concern of malignant change of the lesion, therefore we elect to perform below-knee amputation for her. The pathologic examination confirmed our suspicion and the patient made an uneventful recovery and fares well during the follow-up period eversince.
