Abstract Background Neurofibromatosis type 1 (NF1) is an autosomal dominant condition with a high rate of new mutation and variable expression. Diffuse neurofibroma of the epidermis invading deeper organs is rare.We report a case of diffuse subcutaneous neurofibroma in the thoracoabdominal wall which had invaded the diaphragm and caused diaphragmatic eventration. Case presentation We describe a patient with diffuse neurofibroma of the chest and abdomen who was admitted to the hospital due to sudden abdominal pain and a possible diaphragmatic hernia. We performed thoracotomy and found that the neurofibroma had invaded the diaphragm and caused diaphragmatic eventration. Conclusions This occurrence has not been reported, and it shows that although neurofibromatosis is a benign disease, it still has the biological behavior of a malignant tumor and may cause a serious impact on and damage to other organs.

Neurofibromatosis type-1 (NF-1), also known as von Recklinghausen disease, is a common autosomal dominant condition occurring in approximately 1/3000 births. NF-1 is known to be associated with gastrointestinal neoplasms in 2–25 per cent of patients. We report the first case of gastric outlet obstruction with perforation caused by neurofibroma in a patient with NF-1. The literature is reviewed, examining 61 previously reported cases of noncarcinoid gastrointestinal (GI) neoplasms in patients with NF-1 for symptoms, location, and types of neoplasms. Neoplasms were located most often in the small intestine (72%). Neurofibromas, found in 52 per cent of patients, were the most frequently diagnosed benign neoplasms followed by leiomyomas (13%), ganglioneurofibromas (9.8%), and gastrointestinal stomal tumor (GIST) (6.5%). Adenocarcinoma was present in 23 per cent of patients. Patients with NF-1 and GI symptoms are at risk for gastrointestinal neoplasms from which symptomatic patients are likely to experience significant morbidity.

Abstract Background Central precocious puberty is a condition characterized by precocious activation of the hypothalamic-pituitary-gonadal axis. It may be idiopathic or secondary to organic causes, including syndromes such as Neurofibromatosis type 1 (NF1). Case presentation We presented a girl of 6 years and 10 months with almost 11 café-au-lait skin macules, without other clinical or radiological signs typical of NF1, and with a central precocious puberty. Genetic analysis evidenced the new variant NM-152594.2:c.304delAp. (Thr102Argfs*19) in SPRED1 gene, which allowed to diagnose Legius syndrome. Conclusions We report for the first time a case of central precocious puberty in a girl with Legius syndrome. The presence of central precocious puberty in a child with characteristic café-au-lait macules should suggest pediatricians to perform genetic analysis in order to reach a definitive diagnosis. Further studies on timing of puberty in patients with RASopathies are needed to better elucidate if this clinical association is casual or secondary to their clinical condition.

Neurofibromatoses are a set of different genetic disorders that have a common characteristic of the appearance of nervous system tumors. There are three forms of the disease, of which type 1 neurofibromatosis (NF 1) is the most common. NF 1 is an inherited autosomal-dominant disease, with a high rate of new mutations. In addition to the many physical manifestations and complications that occur in persons with NF 1, there are also numerous cognitive difficulties, including lower general intellectual functioning, learning difficulties, but also problems in attention, visual abilities, executive functions, and speech. Attention disorders are up to three times more common in people with NF 1, while learning disabilities are present in more than half of these subjects. Disturbances in the field of visuospatial perception are recognisable even in the preschool period. About 80% of children with NF1 exhibit various speech and language disorders: slow early speech development, slower vocabulary enrichment, syntactic, semantic and phonological speech disorders. Disruption of executive functions will manifest itself in the areas of working memory, organisation, planning / problem solving. This will reflect as the underperformance in academic achievement. Nearly one-third of these persons have emotional and social problems.

Neurofibromatosis type 1 (NF1) is an autosomal dominant tumor predisposition syndrome that affects children and adults. Individuals with NF1 are at high risk for central nervous system neoplasms including gliomas. The purpose of this review is to discuss the spectrum of intracranial gliomas arising in individuals with NF1 with a focus on recent preclinical and clinical data. In this review, possible mechanisms of gliomagenesis are discussed, including the contribution of different signaling pathways and tumor microenvironment. Furthermore, we discuss the recent notable advances in the developing therapeutic landscape for NF1-associated gliomas including clinical trials and collaborative efforts.

Neurofibromatosis type 1 (NF-1) is an autosomal dominant genetic disorder, mainly characterized by skin and peripheral nervous system abnormalities. Uncommonly, NF-1 may be associated with peripheral or supra-aortic trunks artery aneurysms. We report a case of symptomatic multiple occipital artery aneurysms detected in a 53-year-old woman affected by sporadic NF-1. An endovascular approach was performed to exclude aneurysms and to stop laterocervical spontaneous hematoma.

CONTEXT: Neurofibromatosis type 1 (NF-1) is the most prevalent autosomal dominant genetic disorder among humans. Moyamoya disease is a cerebral vasculopathy that is only rarely observed in association with NF-1, particularly in the pediatric age range. The present study reports an occurrence of this association in an infant. CASE REPORT: An eight-month-old female presented convulsive seizures with clonic movements. The patient suffered an ischemic stroke with hemiparesis. Magnetic resonance imaging revealed radiological findings compatible with moyamoya disease. The diagnosis of NF-1 was made at the age of 20 months. CONCLUSION: Despite the rarity of this association in childhood, children with focal neurological symptoms and a diagnosis of NF-1 deserve to be investigated for moyamoya syndrome.

Hereditary Disorders

AbstractThe neurofibromatoses consist of at least two distinct autosomal dominant hereditary disorders. Neurofibromatosis type 1 (NF1) is due to a lesion on chromosome 17q. Neurofibromatosis type 2 (NF2) is caused by a defect on chromosome 22q. The hallmark of NF2 is the development, in the second and third decades, of bilateral acoustic neuromas. NF1 is characterized by the appearance of cafe-au-lait spots and neurofibromas in addition to iris hamartomas, or Lisch nodules, of the eye, during the first and second decades.Ten families were personally studied. A total of 16 members were found to be affected with NF2. A protocol for evaluation and review of subjects and relatives of NF2 families is proposed. A team approach, coordinating the expertise of multiple specialties is recommended.

Neurofibromatosis type 1 is a common, autosomal dominant, monogenetic neurocutaneous disorder. It is characterized by café au lait spots, axillary and inguinal freckling, Lisch nodules, optic pathway gliomas, neurofibromas, and distinctive bony abnormalities. Also associated with this condition are other central nervous system tumors, scoliosis, hypertension, vascular abnormalities, and cognitive issues such as learning disabilities and attention deficit-hyperactivity disorder.

Neurofibromatosis Type 1 (Von Recklinghausen disease) is a common, autosomal dominant hereditary disorder characterized by involvement of multiple tissues derived from the neural crest. Urinary system involvement in neurofibromatosis is a rare condition. Leiomyoma of the bladder is a rare benign mesenchymal tumor. In this case, our experience and approach regarding the bladder leiomyoma development in a patient diagnosed with neurofibromatosis are presented and the literature data has been reviewed.
