Clinical Entities: Hemangiomas

Hemangiomas are non-cancerous tumors made up of blood vessels. They can happen to anyone, but they’re most common in babies. These little red or purple bumps can show up anywhere on the body, but they’re usually found on the head, neck, or trunk.

Types of Hemangiomas

There are two main types of hemangiomas:

• Superficial Hemangiomas: These are the most common type. They stay on the surface of the skin, looking like a strawberry or raspberry. They usually start growing rapidly in the first few weeks of life and then slow down by about 6 months. Most superficial hemangiomas will fade away on their own by the time a child is 5 or 6 years old.

• Deep Hemangiomas: These are less common and grow deeper in the skin or even in internal organs. They can look like a bluish mass or lump. Deep hemangiomas can cause problems like pain, bleeding, or difficulty breathing if they grow in certain areas.

Complications of Hemangiomas

Most hemangiomas are harmless and will go away on their own. However, some can cause complications like:

• Kasabach-Merritt Phenomenon: This is a rare but life-threatening condition that can happen when a hemangioma causes low blood platelets and clotting problems.

• Ulceration: This is when a hemangioma breaks down and forms an open sore.

• Infection: Hemangiomas can become infected if they’re not properly cleaned and cared for.

Treatment Options for Hemangiomas

Most hemangiomas don’t need treatment, but there are a few options available if they’re causing problems. These include:

• Observation: Most hemangiomas will go away on their own, so doctors often recommend just watching and waiting to see how they progress.

• Medication: Propranolol, a blood pressure medication, has been shown to shrink hemangiomas. Other medications like corticosteroids and interferon can also be used.

• Surgery: Surgery may be necessary if a hemangioma is causing significant problems or if it doesn’t respond to medication.

• Laser Therapy: Laser therapy can be used to remove superficial hemangiomas that are causing cosmetic concerns.

Imaging Techniques

• Discuss the role of computed tomography (CT) and magnetic resonance imaging (MRI) in diagnosing hemangiomas.
