Type 1 neurofibromatosis (von Recklinghausen disease).

Type 1 neurofibromatosis (NF1), or von 
Recklinghausen disease, is a genetic disorder that is well known for its clinical features. 
Effective treatment modalities for NF1 have not yet been established. The advent of new treatment options for NF1 such as topical vitamin D3 analogues, lovastatin, rapamycin (or sirolimus), and imatinib mesylate has added new dimensions that require further investigation to provide the greatest benefit to patients.
