Juvenile angiofibroma

Definition

Juvenile angiofibroma is a noncancerous growth of the back of the nose or upper throat.

Alternative Names

Nasal tumor; Angiofibroma - juvenile; Benign nasal tumor; Juvenile nasal angiofibroma; JNA

Causes

Juvenile angiofibroma is not very common. It is usually found in adolescent boys. The tumor contains many blood vessels, spreads within the area in which it started (locally invasive), and can cause bone damage.

Symptoms

Exams and Tests

The doctor may see the angiofibroma when examining the upper throat.

Tests that may be done include:

Biopsy is generally not recommended due to the high risk of bleeding.

Treatment

You will need treatment if the angiofibroma is growing larger, blocking the airways, or causing repeated nosebleeds. In some cases, no treatment is needed.

Surgery may be needed to remove the tumor. The tumor may be hard to remove if it is not enclosed and has spread to other areas. Newer surgery techniques that place a camera up through the nose have made tumor removal surgery less invasive.

A procedure called embolization may be done to prevent the tumor from bleeding. The procedure may correct the nosebleeds by itself, but it is usually followed by surgery to remove the tumor.

Outlook (Prognosis)

Although not cancerous, angiofibromas may continue to grow. Some may disappear on their own.

It is common for the tumor to return after surgery.

Possible Complications

  • Anemia
  • Pressure on the brain (rare)
  • Spread of the tumor to the nose, sinuses, and other structures

When to Contact a Medical Professional

Call your health care provider if you often have nosebleeds.

Prevention

There is no known way to prevent this condition.
