Pyogenic granuloma

Definition:

Small, reddish, elevated highly, vascular (blood vessel) lesions appearing on the skin; often at the site of trauma.

Causes, incidence, and risk factors:

The exact cause of pyogenic granulomas is unknown but they do appear frequently following injury. They are often on the hands and arms or face and because they bleed easily they can be very annoying. Pyogenic granulomas are common in children. They rarely exceed 1 centimeter in diameter.
