Blue rubber bleb nevus syndrome is a rare disorder consisting of multiple venous system malformations predominantly involving the skin, musculoskeletal system, and gastrointestinal tract. Lesions may involve any tissue and have a potential for severe bleeding and death.
Presentation
The name blue rubber bleb nevus syndrome is derived from the rubber-like consistency on palpation of the cutaneous lesions. They present as dark blue compressible papules that may or may not be painful [1] and measure from millimeters to centimeters in diameter. These cutaneous nevi do not bleed spontaneously but are fragile and may be flat, elevated or pedunculated.
Patients have nonspecific complaints like asthenia caused by chronic hemorrhage due to acute blood loss following hematemesis, rectal bleeding or melena, hemoptysis, hematuria, epistaxis or nasal bleeding [2] or signs of hemothorax or hemopericardium. Occipital lobe bleeding associated with blue rubber nevus syndrome has been described, leading to blindness [3]. Similar lesions may be encountered in any [4] type of tissue: glandular, muscular, genital, bone, heart, lung, renal, pericardium and peritoneum [5] [6].
Nevi are usually present and diagnosed at birth and have a natural tendency to grow and multiply or even invade neighboring structures as the child grows older, but malignant transformation has not been reported yet. Nevi located close to bones may cause bowing deformity, while those in the neighborhood of joints may lead to hemarthrosis and affect joint mechanics. Their histological nature, consisting of dysplastic veins with abnormal walls may cause consumption coagulopathy that exacerbates blood loss.
Entire Body System
- Anemia
This disease is often associated with sideropenic anemia and occult bleeding. We report the case of chronic severe anemia in an old patient under oral anticoagulation treatment for chronic atrial fibrillation. [ncbi.nlm.nih.gov]
- Soft Tissue Mass
He presented with a rubber-like soft-tissue mass in the left knee and the right side of the neck, recurrent pain, and fixed flexion contracture of the knee. [ncbi.nlm.nih.gov]
Soft tissue masses not specific for hemangiomas can be revealed by CT scans. Selective arteriography and scintillography are useful in cases of active bleeding. In our case, the massive bleeding indicated surgical treatment. [scielo.br]
Physical examination indicated that the blue-black rubber-like soft-tissue masses ranging from 5 mm to 5 cm were on the neck, upper and lower limbs, chest walls, and back (Fig. 1 a). [karger.com]

Cardiovascular
- Vascular Disease
Abstract Blue rubber bleb nevus syndrome (BRBNS) is a rare congenital vascular disease associated with important morbidity and non-insignificant risk of mortality in cases of severe gastrointestinal or neurological involvement. [ncbi.nlm.nih.gov]
主要主题词: Esophagus; Gastrointestinal Neoplasms; Nevus, Blue; Skin Neoplasms; Vascular Diseases [paper.medlive.cn]
It is a congenital vascular disease with various phenotypic patterns. BRBNS is most common in childhood and adolescence, with only a few cases occurring in adults. [news-medical.net]
Eyes
- Enophthalmos
A 27-year-old white woman presented with enophthalmos in the right eye. The visual acuity was 20/20 in both eyes. External examination showed 7 mm of enophthalmos of the right eye with deepened superior palpebral sulcus compared with the left eye. [ncbi.nlm.nih.gov]

Neurologic examination showed right enophthalmos and ptosis, which had been present from early childhood. Motor and sensory findings were normal. [ajnr.org]
Workup
Clinical examination may reveal signs of chronic or acute posthemorrhagic anemia or of other complications like volvulus, bowel infarction or intussusception. Mobility may be impaired due to the extension of the lesion inside the joint [7] or due to spinal cord compression [8]. Patients may exhibit dyspnea caused by severe anemia or recurrent thromboembolism and pulmonary hypertension [9] or cyanosis induced by pulmonary stenosis [10].
Workup should include a complete blood count, serum iron levels, a stool sample for occult blood and a urine sample that may detect hematuria.
Skeletal and articular involvement is diagnosed using simple X-rays and may include focal lytic defects or cortical remodeling [11]. The extent of gastrointestinal lesions is best evaluated using superior digestive endoscopy or colonoscopy, while magnetic resonance imaging [12], computer tomography [13] and Technetium-99 scintigraphy [14] detect extracutaneous lesions and bleeding. Magnetic resonance imaging is especially useful in diagnosing liver, spleen and pancreatic lesions, while capsule endoscopy is emerging as an alternative to evaluate gastrointestinal nevi [15]. This is particularly useful since barium studies, the cheaper and more widely accessible alternative only shows polypoid structures and is unable to differentiate between polyps and nevi, creating confusion.
Visceral angiography is not usually indicated, unless performed for other reasons in the same area, despite the fact that it might offer valuable information during the venous phase.
If the extent of the disease is not easily appreciated using noninvasive measures, an exploratory laparoscopy should be performed, especially since this could limit the area of the small bowel to be resected.

We report the case of a 37-year-old woman, with known BRBNS, who acquired an intractable cough with a radiograph revealing multiple pulmonary nodules. [ncbi.nlm.nih.gov]

Nevi in the intestines can bleed spontaneously and cause anemia or more serious complications. Other symptoms vary depending on the organ affected. [rarediseases.info.nih.gov]
Treatment
There are currently no effective treatments for BRBNS. Here, we report a case of successful treatment with a small dose of sirolimus of a BRBN patient with a de novo gene mutation. [ncbi.nlm.nih.gov]
Some patients also receive treatment due to cosmetic problems[ 10, 13, 14, 33 ]. The treatment of GI BRBNS is determined by the extent of intestinal involvement and severity of the disease. [doi.org]
What Are the Treatment Options for Blue Rubber Bleb Nevus Syndrome? The treatment should be recommended according to the severity of the blue rubber bleb nevus syndrome. [icliniq.com]
Prognosis
Prognosis and Treatment The prognosis of BRBN is dictated by the extent of intestinal involvement and the presence of other organ involvement. [ncbi.nlm.nih.gov]
Rarely, CNS involvement can be fatal. [11] The prognosis for blue rubber bleb nevus syndrome (BRBNS) depends on the extent of visceral organ involvement and complications related to the degree of symptoms. [emedicine.com]
Etiology
The etiology of blue rubber bleb nevus syndrome (BRBNS) remains unknown. [5] The literature suggests that this condition occurs sporadically. [5, 6] A few reported cases have been associated with an autosomal dominant inheritance pattern, for which a [emedicine.com]
Etiology Underlying etiology is not known. BRBNS appears to be a sporadic event (although a small number of autosomal dominant cases has been reported). [dermatologyadvisor.com]
Epidemiology
In addition, we review the available literature on the epidemiology, clinical features, associated conditions, diagnosis and treatment. [ncbi.nlm.nih.gov]
A world wide website was established to determine the epidemiology, natural history, and clinical aspects of BRBNS. Results: 35 individuals with the diagnosis of BRBNS responded to the website. Only 20 fulfilled the definition of BRBNS. [nature.com]
Summary Epidemiology More than 200 cases have been published so far, but prevalence is unknown. [orpha.net]
Pathophysiology
The detailed clinical, endoscopical and histopathological description is given as a wide range of differential diagnosis of vascular lesions based on pathophysiology and updated classification of vascular lesions. [termedia.pl]
The disease shows no predilection for gender.[5] Cutaneous manifestations typically present at birth or within early childhood while visceral involvement typically manifests in early adulthood.[3] Etiology and Pathophysiology The etiology and pathophysiology [eyewiki.aao.org]

Prevention
The patient was treated with octreotide to prevent rebleeding. During the 12 months of treatment he had no gastrointestinal bleeding episodes or anaemia. Then repeat capsule endoscopy showed that the small bowel vascular lesions were unchanged. [ncbi.nlm.nih.gov]
Current medical research has not established a way of preventing Blue Rubber Bleb Nevus Syndrome If there is a family history of BRBNS, then genetic testing of the expecting parents (and related family members) and prenatal diagnosis (molecular testing [dovemed.com]
