HemangiomaA hemangioma is an abnormal build up of blood vessels in the skin or internal organs. It is also described as a congenital benign skin lesion consisting of dense, usually elevated masses of dilated blood vessels". In most cases, hemangiomas will disappear over time. They are formed either during gestation or appear during the first few weeks of life and may present as a birthmark. Hemangiomas are the most common childhood tumor occurring in approximately ten percent of Caucasians, and are less prevalent in other races. Females are three to five times more likely to have hemangiomas than males. Hemangiomas can be vivid superficial lesions, known as capillary hemangiomas , or they can be deep bluish swelling, known as cavernous hemangiomas. Sometimes they can be both superficial and deep. Approximately eighty percent are located on the face and neck, with the next most prevalent location being the liver. Although hemangiomas are benign, some serious complications can occur. The cause of hemangioma is currently unknown; however, several studies have suggested the importance of estrogen signaling in hemangioma proliferation. In 2007, a paper from the Stanford Children's Surgical Laboratory revealed that localized soft tissue hypoxia coupled with increased circulating estrogen after birth may be the stimulus. There is also a hypothesis presented by researchers at Harvard and the University of Arkansas that maternal placenta embolizes to the fetal dermis during gestation resulting in hemangiomagenesis, yet Duke researchers conducted genetic analyses of small nucleotide polymorphisms in hemangioma tissue compared to the mother's DNA that contradicted this notion. More research is required in order to fully understand the explosive nature of hemangioma growth which will hopefully yield targeted therapeutics to treat its most complicated presentations.
