Pyogenic Granuloma

A pyogenic granuloma is a rapidly growing lesion that bleeds easily. This lesion is common in children and young adults. It often occurs in areas of previous trauma including acne cysts. It is believed that this lesion is formed when capillary blood vessels start growing rapidly in response to trauma to the skin.

Pyogenic Granuloma Appearance

A typical pyogenic granuloma is a solitary red papule that grows rapidly over several weeks.

It is typically less than 1 cm and has a glistening, moist surface. The base of the lesion is often red and scaly. Pyogenic granulomas occur most commonly on the head, neck, and fingers.

Pyogenic Granuloma Diagnosis

The diagnosis can be made clinically, based on the typical appearance and location. When the diagnosis is in question, a biopsy can be performed.

Pyogenic Granuloma Treatment

A pyogenic granuloma is often removed by shaving it off and cauterizing the base with electrosurgery. It often bleeds copiously during removal. It is important that the blood vessels feeding the lesion at the base are destroyed or it can recur. In some cases, pulsed-dye laser can be used to treat small lesions, especially in children.
