Vascular malformations, tumors and hemangiomas all refer to a variety of non-cancerous birthmarks and lesions. Boston Children's Hospital is home to internationally renowned physicians for their expertise and innovative contributions to this highly specialized field.

Hemangiomas

  • Infantile hemangiomas are the most common type of vascular anomaly
  • They are a benign (noncancerous) tumor
  • Occur in 4 to 10 percent of infants and more frequently in premature babies
  • Growths are typically noticed in the first two weeks of life
  • They enlarge rapidly, outpacing the rest of the body's growth for the first year
  • After infancy, they slowly regress
  • Usually fully involutes (shrink) by 5 to 7 years old
  • Some residual fatty tissue or thin skin may remain after involution

Vascular malformations

  • Vascular malformations are benign (non-cancerous) lesions

  • They are present at birth, but may not become visible for weeks or months after birth

  • Unlike hemangiomas, vascular malformations do not have a growth cycle and then regress but instead continue to grow slowly throughout life.
