Pyogenic granuloma

  • Definition
    • Pyogenic granulomas are small, raised, and 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.

  • Alternative Names
    • Lobular capillary hemangioma

  • Causes
    • 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
    • Signs of a pyrogenic granuloma are:

      • A small red lump on the skin that bleeds easily
      • Often found at the site of a recent injury
      • Usually seen on hands, arms, and face, but they may develop in the mouth (most often in pregnant women)
  • Exams 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:

  • Outlook (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.

  • Possible Complications
    • These problems may occur:

      • Bleeding from the granuloma
      • Return of the condition after treatment
  • When to Contact a Medical Professional
    • Call your health care provider if you have a skin bump that bleeds easily or that changes appearance.
