An oral irritated fibroma is a type of angiofibroma that presents as a small |bump in the mouth.[1] It tends to be firm, smooth, and dome-shaped or pedunculated typically on the inside of a cheek.[1] It is usually the same color as the rest of the mouth lining, and may be ulcerated or rough and scaly.[1]
It is thought to be due to chronic irritation such as cheek or lip biting, or rubbing from a rough tooth or denture.[1]
