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.
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 and pregnant women.
Signs of a pyogenic 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)

These problems may occur:
- Bleeding from the lesion
- Return of the condition after treatment
