Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder, characterized by multifocal venous malformations predominantly affecting skin, soft tissues, and gastrointestinal (GI) tract. Its presentation is usually sporadic although cases of autosomal dominant inheritance have been reported. Usually seen in children, BRBNS presentation in adults is rare. Most common symptoms of GI tract involvement are iron deficiency anemia and bleeding. We present a case of 16-year-old boy, who presented with recurrent anemia requiring multiple blood transfusions.

| Introduction|| |
Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder, first reported by William Bean in 1958. The syndrome is characterized by vascular malformations of the skin, soft-tissue, gastrointestinal (GI) system, and less often, other organ systems. The clinical manifestations depend on the organ involvement, and the condition is often diagnosed based on the presence of characteristic cutaneous lesions with or without GI bleeding and/or the involvement of other organs. We present a case of 16-year-old boy, who presented with recurrent anemia requiring multiple blood transfusions.
| Case Report|| |
A 16-year-old boy presented to our outpatient department with symptoms of tiredness and easy fatigability for 3 years. He gave a history of being evaluated for similar complaints in the past in an outside medical facility. He was diagnosed to have iron deficiency anemia and had received multiple blood transfusions. The patient had no significant medical history apart from intermittent abdominal pain and blackish color stool for 3 years. He denied having hematochezia, bleeding gums, or recurrent epistaxis, hemoptysis, hematemesis, and dyspnea. He appeared pale at presentation, but was hemodynamically stable, with a hemoglobin level of 6.7 g/dL. On physical examination, he had multiple subcutaneous nodules with bluish hue (size 0.5–2.5 cm) over arms, nails, trunk, and buttocks [Figure 1]a, which were soft, easily compressible, and promptly refilled after compression. The size of the lesions varied from 0.5 to 3.0 cm. On further interrogation, he gave a history of the presence of these subcutaneous nodules since childhood. These had increased in size and in number over time. He had no discomfort and had never attended hospital for these nodules.
Investigations revealed microcytic hypochromic anemia with normal platelet and leukocyte count. His random blood sugar, renal, and liver biochemistry were normal. His iron profile was suggestive of iron deficiency anemia with raised total iron binding capacity. His esophagogastroduodenoscopy (EGD) revealed purpulish-blue multiple vascular venous malformations in right arytenoid, stomach, and duodenum [Figure 2]a,[Figure 2]b,[Figure 2]c without any evidence of bleed. Colonoscopy revealed similar multiple venous vascular malformations in colon [Figure 3]a. On the basis of the above findings, the diagnosis of BRBNS was made and to rule out involvement of other organ system magnetic resonance imaging of the brain and spinal cord and ultrasonogram abdomen were done, which were normal. As the patient had no active bleed, he was given iron supplementation. Two weeks later, a routine blood test showed that the hemoglobin was 7.7 g/dl. He was discharged and asked to follow-up monthly in outpatient department.

BRBNS was reported by William Bean in 1958; hence, also known as Bean Syndrome. Only 200 case reports have been published in literature. Most of the cases of BRBNS have been reported in Caucasians, and in African American, it is even rarer. Jin et al. after reviewing the literature found that cutaneous angiomas were seen in 93%, followed by GI hemangiomas in 76% (our case had cutaneous and GI hemangioma). Other organs, such as the central nervous system (13%), liver (11%), and muscles (9%) were also involved. Multiple organs can be involved in a single patient.
Among the cases reported in the literature, the female-to-male ratio was approximately 1:1, indicating that there is no gender difference in BRBNS. The lesions are often present from birth or early childhood though it can also appear in adults or elderly. The size and number of lesion grows with time.
The pathogenesis BRBNS is uncertain although autosomal inheritance has been identified in several familial cases associated with chromosome 9p; the majority of cases are sporadic., Mogler C found that c-kit was detectable predominantly in smaller vessels within their patient's tissues, suggesting that the stem cell factor/c-kit signaling axis may be involved in the constant growth of venous malformations.
The clinical manifestations depend on the organ involvement. The cutaneous lesions are characterized as rubbery, soft, tender and hemorrhagic, easily compressible, and promptly refill after compression. The other two types of lesions are large disfiguring cavernous lesions and blue-black irregular macules or papules. The cutaneous lesions are usually asymptomatic, but some complaint of pain or sweating. Pain may be caused by contraction of smooth muscle fibers surrounding the angioma and sweating possibly due to the proximity of the nevi to sweat glands. GI hemangiomas may appear in any position from the mouth to the anus. The most common symptoms in the GI tract are bleeding and secondary iron deficiency anemia and may also present with severe complications such as rupture, intestinal torsion, and intussusception. Hemangiomas in the brain or spinal cord can lead to cerebral infarction and spinal cord compression, respectively.
BRBNS is often diagnosed based on the presence of characteristic cutaneous lesions with or without GI bleeding and/or the involvement of other organs. Biopsy is not required routinely for diagnosis. Apart from a physical examination and endoscopy, ultrasonography (USG), radiographic images, computed tomography, and magnetic resonance imaging are also useful for the detection of affected visceral organs. Histological examination revealed cavernous venous dilatations, with a thin wall of smooth muscle cells lined by a simple layer of endothelial cells.
The cutaneous lesions are usually asymptomatic and do not require treatment. When lesions occur in higher risk areas of trauma or in joints, treatment may be required, including surgery, sclerotherapy or laser photocoagulation.
The treatment of GI BRBNS is determined by the extent of intestinal involvement and severity of the disease.
If bleeding is minor or intermittent, conservative treatment, such as blood transfusions and iron supplementation, is recommended due to high recurrence of the disease (our patient presented with anemia without any significant bleed or complication on upper and lower GI endoscopy, so managed conservatively and kept on follow-up).
For more significant hemorrhages or other complications, such as rupture, intestinal torsion, and intussusceptions, surgical resection, endoscopic sclerosis, and laser photocoagulation, have been proposed.,, GI lesions should be identified and must be localized before surgical resection.
Yuksekkaya et al. first reported the use of low-dose sirolimus (an antiangiogenic agent) in an 8-year-old girl with BRBNS characterized by recurrent severe GI bleeding. After sirolimus, vascular lesions reduced in number and GI bleeding and muscle hematomas disappeared.
The prognosis of BRBNS depends on organs involved and the extent of involvement. Most patients can live a long life with the disease; however, the quality of life is limited due to GI bleeding, oral drug therapy, and blood transfusions.
