Objective: An inferior vena cava (IVC) aneurysm is a rare but potentially life-threatening entity. We successfully embolized an IVC aneurysm in a patient with history of blue rubber bleb nevus syndrome, a rare syndrome with multiple venous malformations. This new case was added to a literature review of previously reported cases, to analyze the management algorithm. Read More

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder that is characterized by multiple dome-shaped cutaneous venous malformations on the skin and visceral organs. Typical extra-cutaneous lesions have the appearance of blueish nipple-shaped nodules that can easily compress and refill. We described a rare case of a 23-year-old female with BRBNS and tuberous sclerosis complex (TSC) that presented with central nervous system (CNS) involvement including unprovoked focal impaired awareness seizure.

Background: Blue rubber bleb nevus syndrome (BRBNS) is a rare vascular disease, difficult to diagnose and choose a treatment method, especially in young children. There are several limiting factors to the use of enteroscopy for diagnostics and treatment in pediatric patients, in general. The literature on BRBNS cases is limited and presents various therapeutic approaches. Read More

Objective: Vascular malformations arise from defects in the morphologic development of the vascular system and can have an impact on quality of life and/or lead to severe complications. To date, vascular malformations are frequently managed by invasive techniques, after which recurrence is common. Sirolimus, a downstream inhibitor of the phosphatidylinositol 3 kinase/AKT pathway and best known for its immunosuppressive effect, has been used off-label for lesions for which approved therapies were associated with unsatisfactory results or recurrence.

Introduction: Blue rubber bleb nevus syndrome (BRBNS) is a rare systemic venous malformation (VM) disease. The characteristic gastrointestinal (GI) bleeding from multiple VM lesions causes severe chronic anemia which renders most patients depend on lifelong blood transfusion and frequent endoscopic treatment with dismayed outcomes. Although recent case reports suggest that oral sirolimus (rapamycin) is effective, a comprehensive evaluation of its efficacy and safety is in need. Read More

Blue rubber bleb nevus syndrome is a rare vascular syndrome characterized by continuous eruption of vascular nodules in the skin, mucous membranes, and solid organs due to somatic activating mutations of the angiopoietin receptor TEK gene. It may be complicated by acute life-threatening hemorrhage and localized intravascular coagulation. We report an 11-year-old girl with complicated blue rubber bleb nevus syndrome treated with sirolimus since the age of 2. Read More

The keystone flap is well known to plastic surgeons and is frequently utilized for its ease of implementation, limited donor site morbidity, and favorable aesthetic outcomes. Although keystone flaps have been described in reconstruction of myelomeningocele defects, there have been no reports of their application to infants with large vascular malformations. This case illustrates the utilization of a keystone flap in reconstruction of a large posterior trunk defect that resulted from excision of a massive venous malformation in an 8-week-old infant with blue rubber bleb nevus syndrome.

The Dutch ophthalmologist, Jan van der Hoeve, first introduced the terms phakoma/phakomata (from the old Greek word "ϕαχοσ" = lentil, spot, lens-shaped) to define similar retinal lesions recorded in tuberous sclerosis (1920) and in neurofibromatosis (1923). He later applied this concept: (a) to similar lesions in other organs (e.g. Read More

To study the clinical effect of oral sirolimus in the treatment of children with blue rubber bleb nevus syndrome (BRBNS) in the gastrointestinal tract, a retrospective analysis was performed on the clinical data and follow-up results of two children with BRBNS treated by sirolimus. The two children with BRBNS had gastrointestinal bleeding and anemia and were treated with sirolimus at a dose of 1 mg/day as part of treatment. The plasma concentration of the drug was maintained between 2. Read More

Rationale: Blue rubber bleb nevus syndrome (BRBNS) is an extremely rare disorder characterized by multifocal venous malformations involving various organs such as the skin and gastrointestinal tract. Severe complications of BRBNS, such as intussusception, volvulus, and intestinal infarction are rarer and require surgery. This report describes a 33-year-old male of BRBNS complicated with intussusception that was successfully diagnosed and treated with surgery. Read More

Background: Blue rubber bleb nevus syndrome (BRBNS) is a rare congenital disease characterized by multifocal venous malformations. It remains a considerable challenge in treating the gastrointestinal (GI) venous malformations due to multiple lesions throughout the GI tract, and the likelihood of recurrence. We report a case study of BRBNS in the GI tract, in which GI venous malformations and related GI bleeding were successfully treated with a combination of multiple endoscopic procedures. Read More

Blue rubber bleb nevus syndrome (BRBNS), also called Bean's syndrome, is a rare disease associated with multiple venous malformations in the skin and gastrointestinal (GI) tract. Dermatological lesions, which are the first clinically visible manifestations, appear as skin-colored compressible protuberances or as dark-blue venous nodules, rubbery in consistency. Central nervous system (CNS) manifestations are rare, variable, non-specific, and tend to occur late in the disease, mainly reported as seizures and focal neurological deficits secondary to compression.

Blue rubber bleb nevus syndrome (BRBNS) is a rare congenital vascular anomaly syndrome characterised by multifocal venous vascular malformations. It involves skin, central nervous systems, liver, muscles and gastrointestinal (GI) tract resulting in intestinal haemorrhage and anaemia. Patients with BRBNS experience severe chronic anaemia without any diagnosis requiring multiple transfusions and hospitalisations. Read More

Background And Objective: Blue rubber bleb nevus syndrome (BRBN) or Bean syndrome is a rare Venous Malformation (VM)-associated disorder, which mostly affects the skin and gastrointestinal tract in early childhood. Somatic mutations in TEK have been identified from BRBN patients; however, the etiology of TEK mutation-negative patients of BRBN need further investigation.

Methods: Two unrelated sporadic BRBNs and one sporadic VM were firstly screened for any rare nonsilent mutation in TEK by Sanger sequencing and subsequently applied to whole-exome sequencing to identify underlying disease causative variants. Read More
