The most frequent site of occurrence is the soft tissues adjacent to the mandible.
Lesions appear as firm, painless, poorly demarcate masses with a variable growth rate
Oral fibroma presents as a firm smooth lump in the mouth. It is usually the same colour as the rest of the mouth lining but is sometimes paler or, if it has bled, may look a dark colour. The surface may be ulcerated due to trauma, or become rough and scaly. It is usually dome- shaped but may be on a short stalk like a polyp (pedunculated). If it has developed under a denture it may be flat with a leaf-like shape.
