What Causes Hemangioma in Adults?

Hemangioma or birth mark

Hemangiomas are typically vascular growths or tumors made up of abnormal blood vessels. They are more commonly known to occur in infants and children (infantile hemangiomas), but they can also develop in adults. The exact cause of hemangiomas in adults is not always clear, and they may have different characteristics compared to those in children. Several factors may contribute to the development of hemangiomas in adults:

  • Congenital factors: Some individuals may have had a small, undetected hemangioma since birth that grows or becomes noticeable in adulthood. These are sometimes referred to as congenital hemangiomas.
  • Trauma or injury: Physical trauma or injury to an area of the body can sometimes trigger the formation or growth of a hemangioma. This is known as a traumatic hemangioma.
  • Hormonal changes: Some hemangiomas in adults may be influenced by hormonal changes. For example, hormonal fluctuations during pregnancy or menopause can affect blood vessels and may lead to the development or enlargement of hemangiomas.
  • Genetic predisposition: While not well understood, there may be genetic factors that increase the likelihood of developing hemangiomas in some individuals.
  • Radiation exposure: Radiation therapy, especially when applied to a specific area of the body, can increase the risk of developing vascular abnormalities, including hemangiomas.
  • Pre-existing vascular conditions: Adults with certain pre-existing vascular conditions, such as Sturge-Weber syndrome or Klippel-Trenaunay syndrome, may be more susceptible to the development of hemangiomas.

It’s important to note that most hemangiomas in adults are not aggressive or dangerous, and they may not require treatment unless they cause symptoms or cosmetic concerns. However, if an adult develops a new or rapidly growing vascular lesion or experiences any associated symptoms, it is crucial to consult a healthcare provider. A medical evaluation can help determine the nature of the lesion and whether any further testing or treatment is necessary. In some cases, treatment options may include laser therapy, medication, or surgical removal, depending on the size, location, and symptoms associated with the hemangioma.
