Definition

A benign (not cancer) blood vessel tumor that usually forms on the skin. It may also form on mucous membranes and inside capillaries (small blood vessels) or other places on the body. Pyogenic granulomas usually appear as raised, bright red lesions that may grow quickly and bleed a lot. The lesions are sometimes caused by injury or use of certain medicines and often come back after treatment. They usually occur in older children and young adults but may occur at any age. Pyogenic granulomas are a type of vascular tumor. Also called lobular capillary hemangioma.
