A hemangioma is a benign tumor of blood vessels, often appearing as a red to purple raised lesion on the skin. These lesions are most commonly found in infants and are known for their rapid growth during the first year of life, followed by a slow involution phase.

Signs and Symptoms

Hemangiomas typically present as a red to purple raised lesion on the skin. They can vary in size and may appear anywhere on the body, but are most commonly found on the face, scalp, chest, or back. While most hemangiomas are superficial, some may have a deeper component, leading to a bluish hue.

Complications

Although hemangiomas are generally benign, they can lead to complications such as ulceration, bleeding, and infection. In rare cases, they may interfere with vital functions if located near the eyes, nose, or mouth.

Causes

The exact cause of hemangiomas is not well understood, but they are believed to result from genetic factors. Certain risk factors, such as premature birth and female gender, have been associated with a higher incidence of hemangiomas.

Diagnosis

Diagnosis of hemangiomas is primarily based on physical examination. In some cases, imaging studies such as ultrasound or MRI may be used to assess the extent of deeper lesions.

Treatment

Most hemangiomas do not require treatment and will resolve on their own by age 10. However, in cases where treatment is necessary, options include observation, beta-blockers such as propranolol, and laser therapy.

Prognosis

The prognosis for hemangiomas is generally excellent, with most lesions resolving completely by age 10. However, some may leave residual skin changes or scarring.
