Pyogenic granuloma is caused by a small growth of blood vessels. These are not medically concerning, but can be distressing to families because of how easily they bleed. Because of the tendency to bleed, it is usually recommended that pyogenic granulomas be removed.
Pyogenic granulomas are common growths of blood vessels that can occur on the skin or mucosa.1 The most common areas of involvement are the trunk and arms.1 They are typically bright red to red-brown, but sometimes can appear black if there has been frequent bleeding due to the development of a scab-like surface. The surface may be smooth or more lobulated (cauliflower-like).1 The size of pyogenic granulomas can be highly variable. They may develop at any age.
The diagnosis is most often made clinically. When in doubt, a skin biopsy may be performed which can also treat the pyogenic granuloma.
