Neurofibromatosis Type 1

Overview

Neurofibromatosis Type 1 is a relatively common inherited disorder that affects 1 in every 3000 people. 

Patients usually have a particular skin pigmentation (‘café au lait spots’), neurofibromas (nodules on the skin) and bone deformities, including scoliosis of the spine, and are at risk of bone fractures due to osteoporosis. 

Patients with neurofibromatosis type 1 are prone to developing both benign and malignant tumours.

These tumours include: 

  • brain and eye tumours (glioma) 
  • tumours of the nerves 
  • gastrointestinal stromal tumours (GIST) 
  • phaeochromocytoma 
  • small bowel (duodenal) Neuroendocrine Cancer 
  • breast cancer, leukaemia, sarcomas. 
  • pancreatic tumours
