Pyogenic granuloma https://en.wikipedia.org/wiki/Pyogenic_granuloma
Pyogenic granuloma is a common vascular tumor that occurs on both mucosa and skin and appears as an overgrowth of tissue caused by irritation, physical trauma, or hormonal factors. Pyogenic granuloma may be seen at any age and is more common in females than in males. In pregnant women, lesions may appear in the first trimester, increase in incidence until the seventh month, and are often located on the gums. The lesion typically shows a color ranging from red or pink to purple, grows rapidly, and may be smooth or mushroom‑shaped.

Diagnosis and Treatment
If bleeding occurs, prompt surgical excision is recommended.

Pyogenic granuloma, sometimes known as granuloma pyogenicum, refers to a common, acquired, benign vascular tumor that arises in tissues such as the skin and mucous membranes. It is more accurately called a lobular capillary hemangioma. The lesion grossly appears as a solitary, red, pedunculated papule that is very friable. Less commonly, it may present as a sessile plaque. It shows rapid exophytic growth, with a surface that often undergoes ulceration. It is often seen on cutaneous or mucosal surfaces. Among the latter, it is most commonly seen within the oral cavity.
