Hemangioma

A hemangioma is a benign growth made up of extra blood vessels. It most commonly appears on the skin or in internal organs, especially the liver. Hemangiomas are usually present at birth or develop shortly afterward and are more common in infants. Most hemangiomas are harmless and do not require treatment, often shrinking or disappearing over time.

Symptoms

Symptoms of a hemangioma depend on its size, type, and location.

Common symptoms include:

• Red or purple raised mark on the skin

• Soft, rubbery mass that blanches when pressed

• Rapid growth during early infancy followed by gradual shrinking

• Pain or discomfort if the hemangioma presses on nearby structures

• Ulceration or bleeding in skin hemangiomas

• Symptoms related to organ involvement, such as abdominal pain or fullness

Causes

The exact cause of hemangiomas is not fully understood.

Possible causes include:

• Abnormal growth of blood vessels

• Developmental changes during fetal growth

• Genetic and environmental factors

• More common in premature infants and females

Risk Factors

Certain factors increase the likelihood of developing hemangiomas.

Risk factors include:

• Premature birth

• Low birth weight

• Female sex

• Family history of vascular anomalies

• Caucasian ethnicity

Complications

Most hemangiomas do not cause complications, but some may require medical attention.

Possible complications include:

• Ulceration and infection of skin hemangiomas

• Bleeding following trauma

• Scarring after involution

• Interference with vision, breathing, or feeding if located near vital areas

• Rare complications related to internal hemangiomas

Prevention

There is no known way to prevent hemangiomas, as they develop due to factors present before or shortly after birth. However, early detection and monitoring help prevent complications.

Preventive care strategies include:

• Regular monitoring of infant hemangiomas

• Early medical evaluation for rapidly growing lesions

• Protecting skin hemangiomas from injury

• Prompt treatment if complications arise
