Pyogenic granuloma (also known as a "Eruptive hemangioma", "Granulation tissue-type hemangioma", "Granuloma gravidarum", "Lobular capillary hemangioma", "Pregnancy tumor", and "Tumor of pregnancy") is a vascular lesion that occurs on both mucosa and skin, and appears as an overgrowth of tissue due to irritation, physical trauma or hormonal factors. It is often found to involve the gums, the skin and nasal septum, and has also been found far from the head such as in the thigh.
