Von Recklinghausen disease, or neurofibromatosis, is a congenital

disease primarily affects ectodermal tissues arising from the neural crest. It
is divided into two basic forms: peripheral (type 1) and central (type 2),
characterized by distinct skeletal and soft-tissue
manifestations1-6.
Type-1 neurofibromatosis usually manifests in early childhood and is more
frequent than the type-2 form of the
disease7,8.
Skeletal abnormalities and dysplasias, including erosive or pressure bone
defects, pseudarthroses, and cranial defects, are diagnosed in approximately
80% of patients with type-1 neurofibromatosis. In addition, multiple
nonossifying fibromas that predominantly affect the metaphyseal parts of the
long tubular bones tend to develop in patients with this type of the
disease1.
The most serious, and often fatal, complication of the disease is a

soft tissue of the . . . [Full Text of this Article]
