A pyogenic granuloma is a collection of blood vessels that grow quickly and
abundantly, often at the site of an injury.
What is going on in the body?
The cluster of blood vessels making up the pyogenic granuloma forms a dark red
spot that becomes ulcerated and crusts over. This process usually takes 1 to 2
weeks. It is considered an abnormal healing response. Normally, blood vessels
respond with growth to help heal a traumatic site. In this condition, it's as
if the response is excessive and doesn't know when to turn off.
What are the causes and risks of the disease?
The cause of pyogenic granuloma is unknown. It is most common in children and young adults, and may occur during pregnancy. The hormonal changes that pregnant women and children undergo may be a contributing factor.
