Giant Neurofibroma of the Left Median Nerve Associated With Damage of the Ipsilateral Distal Radius

Abstract

A 74-year-old Caucasian woman presented with a large mass on her left distal radius, which had previously caused a fracture of the bone at this site and the palmar site that was treated with external fixation a year ago. The patient did not mention tumor-related family history and other neoplasms before the fracture of the distal radius. She noticed that the gradually growing mass had appeared after the fracture treatment. A thorough evaluation of the lesion confirmed the diagnosis of a large benign neurofibroma with distal radius impairment. The diagnostic and therapeutic procedure included the complete excision of the tumor and a six-week cast immobilization of the radius. On the final follow-up two years postoperatively, her clinical situation was satisfactory with no signs of recurrence. Although rare, isolated benign neurofibromas of enormous sizes are associated with bone damage. In our view, immediate surgical excision is crucial and enables total recovery postoperatively.
