Pyogenic granuloma

Lobular capillary hemangioma

Last reviewed: November 20, 2012.

Pyogenic granulomas are small, raised, red bumps on the skin. The bumps have a smooth surface and may be moist. They bleed easily because of the high number of blood vessels at the site.

Causes, incidence, and risk factors

The exact cause of pyogenic granulomas is unknown. They often appear following an injury on the hands, arms, or face.

Pyogenic granulomas are common in children.

Symptoms

  • Small red vascular lump that bleeds easily
  • Often found at site of recent injury
  • Usually seen on hands, arms, and face, but may develop in the mouth (most often in pregnant women)

Signs and tests

Your health care provider will do a physical exam to diagnose this condition. You may also need a skin biopsy to confirm the diagnosis.

Treatment

Small pyogenic granulomas may go away suddenly. Larger bumps are treated with surgery, electrocautery, freezing, or lasers.

Expectations (prognosis)

Most pyogenic granulomas can be removed. A scar may remain after treatment. There is a high chance that the problem will come back if the whole granuloma is not destroyed during treatment.

Complications

Calling your health care provider

Call your health care provider if you have a skin bump that bleeds easily or that changes appearance.
