Blue bleb rubber nevus syndrome

Area of Science:

• Vascular biology
• Developmental biology
• Medical genetics

Background:

• Vascular malformations are congenital errors in vessel development during embryogenesis.
• They are classified rheologically into slow-flow (capillary, lymphatic, venous) and fast-flow (arterial, arteriovenous) types.
• These lesions grow with the patient and do not regress spontaneously.

Purpose of the Study:

• To describe venous malformations (VM), focusing on Blue Rubber Bleb Naevus Syndrome (BRBN).
• To highlight the association of BRBN with gastrointestinal VMs and localized intravascular coagulopathy.
• To emphasize the importance of brain MRI screening and multidisciplinary management for BRBN.

Main Methods:

• Review of vascular malformation classification and characteristics.
• Description of Blue Rubber Bleb Naevus Syndrome (BRBN) clinical features.
• Discussion of diagnostic considerations including brain MRI.
• Overview of multidisciplinary management strategies.

Main Results:

• Venous malformations (VM) are ectatic venous channels, often sporadic but can be inherited.
• Blue rubber bleb naevus syndrome presents with cutaneous and gastrointestinal VMs, frequently with localized intravascular coagulopathy.
• Cerebral VMs can occur in BRBN, necessitating brain MRI.

Conclusions:

• Blue rubber bleb naevus syndrome requires comprehensive evaluation, including brain MRI, due to potential cerebral involvement.
• Management of vascular malformations, particularly BRBN, is complex and requires a multidisciplinary approach.
• Early diagnosis and tailored treatment are crucial for managing these congenital vascular anomalies.
