A pyogenic granuloma or lobular capillary hemangioma[3] is a vascular tumor that occurs on both mucosa and skin, and appears as an overgrowth of tissue due to irritation, physical trauma, or hormonal factors.[4][5] It is often found to involve the gums, skin, or nasal septum, and has also been found far from the head, such as in the thigh.[6]
Pyogenic granulomas may be seen at any age, and are more common in females than males. In pregnant women, lesions may occur in the first trimester with an increasing incidence until the seventh month, and are often seen on the gums.[7]
