We report our experience with a synchronous case of gastrointestinal stromal tumor (GIST) and intraductal papillary neoplasm of the bile duct (IPNB) in an elderly woman with neurofibromatosis type 1 (NF-1). A 72-year-old woman presented with a 2-mo history of right upper abdominal pain unrelated to diet and indigestion. Fourteen years earlier, she had been diagnosed with NF-1, which manifested ...

Neurofibromatosis type 1 (NF1) is a common, autosomal dominant genetic disorder with a variety of highly variable symptoms including cutaneous manifestations (such as café au lait spots), Lisch nodules, plexiform neurofibromas, skeletal abnormalities, an increased risk for malignancy, and the development of learning disabilities. The wide clinical variability of expression of the disease phenot...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-200033 DESCRIPTION A 35-year-old black woman with Von Recklinghausen disease (or neurofibromatosis type 1) presented multiple café-au-lait spots, axillary freckling and multiple cutaneous neurofibromas, which were more expressive in the abdomen and trunk (figure...

BACKGROUND McCune Albright syndrome (MAS) is a rare disorder characterized by precocious puberty, café-au-lait spots, and fibrous dysplasia. Its cause is an activating mutation in the GNAS gene, encoding a subunit of the stimulatory G protein, Gsalpha (Gsα). The action of any mediator that signals via Gsα and cyclic AMP can be up regulated in MAS. We had observed gastritis, gastroesophageal ref...

Neurofibromatosis type 1 (NF1) is a common autosomal dominant disorder which displays considerable inter- and intra-familial variability in phenotypic expression. To evaluate the genetic component of variable expressivity in NF1, we examined the phenotypic correlations between affected relatives in 750 NF1 patients from 275 multiplex families collected through the NF-France Network. Twelve NF1-...

INTRODUCTION McCune-Albright syndrome is a complex inborn disorder due to early embryonal postzygotic somatic activating mutations in the GNAS1 gene. The phenotype is very heterogeneous and includes polyostotic fibrous dysplasia, typically involving the facial skull, numerous café-au-lait spots and autonomous hyperfunctions of several endocrine systems, leading to hyperthyroidism, hypercortisol...

INTRODUCTION Neurofibromatosis type 1 (NF1) is the most common neurocutaneous disease, nevertheless the number of publications providing clinical and genetic data from a significant number of children is limited. MATERIAL AND METHODS The available clinical, epidemiological, radiological and genetic data from 239 children with NF1, who attended at a specialist NF1 clinic between January 2011 a...

Noonan syndrome (NS) is a relatively common, clinically variable and genetically heterogeneous developmental disorder characterized by postnatally reduced growth, distinctive facial dysmorphism, cardiac defects and variable cognitive deficits. Other associated features include ectodermal and skeletal defects, cryptorchidism, lymphatic dysplasias, bleeding tendency, and, rarely, predisposition t...

Neurofibromatosis 1 (NF1) is an autosomal dominant disorder associated with a variety of benign and malignant lesions such as café au lait spots, neurofibromas, phaeochromocytomas, pilocytic astrocytomas, and malignant peripheral nerve sheath tumours. With an incidence of 1 in 4000, NF1 is caused by genetic alterations of the NF1 gene located on 17q11.2. Consisting of 60 exons, the NF1 gene is ...

<p class="abstract">Type 1 neurofibromatosis (NF 1) may present with a constellation of symptoms but literature has recorded that the commonest manifestations are orthopedic spinal presentations taking lead. Of manifestations, scoliosis is frequently found compared to others which could include spondylolisthesis or defective pedicles and dural ectasia on radiographs. We reported 15-year-o...
