Figure 15: A–D. Resection of plexiform neurofibroma of the right upper extremity in a patient with NF1, who was very sensitive to pain in this area. A. In this case, the effect of the invasive tumor on the skin is hardly visible. Palpation shows only the superficial portions of the nodular tumors (“bag of worms”). Skin pigmentation in this area is hardly changed. B. Magnetic resonance image indicates a nodular tumor and hyperintense skin covering the tumor-affected region. C. Intraoperative situs reveals a dense conglomerate of enlarged and tumorous peripheral nerves. D. Wound closure by primary intention. E. Female patient with NF1 and history of multiple surgical interventions of the left upper extremity. F. Debulking in the palm region was carried out in order to improve gripping function of the remaining fingers.
