What type of tumor is a hemangioma?

A hemangioma is classified as a benign tumor that arises from an abnormal proliferation of blood vessels, particularly capillaries. This type of tumor is typically characterized by its soft, reddish appearance and is most commonly found in infants and children, although it can occur in adults as well. Hemangiomas usually resolve on their own over time without treatment, making their benign nature significant.

Understanding that hemangiomas are benign helps in patient management, as these tumors are generally not life-threatening and do not spread to other parts of the body like malignant tumors do. This distinction is crucial when assessing skin lesions and determining appropriate treatment options or the necessity for further evaluation.
