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. It is a benign (noncancerous) growth.
Lobular capillary hemangioma
The exact cause of pyogenic granulomas is unknown. They often appear following an injury on the hands, arms, or face.
The lesions are common in children and pregnant women. (A skin lesion is an area of the skin that is different than the surrounding skin.)
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.
Small pyogenic granulomas may go away suddenly. Larger bumps are treated with:
- Surgical shaving or excision
- Electrocautery (heat)
- A laser
- Creams applied to the skin (may not be as effective as surgery)
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 lesion is not destroyed during treatment.
These problems may occur:
- Bleeding from the lesion
- Return of the condition after treatment
When to Contact a Medical Professional
Call your provider if you have a skin bump that bleeds easily or that changes appearance.
