Most frequently, a dense fibrous hyperplasia occurs, often with varying degrees of inflammation and vascularity. As capillary proliferation is considerable, an overlap with pyogenic granuloma occurs. Mucous glands often are present in the specimen and may show a chronic sialadenitis. Occasionally, the glands may have an associated lymphoid hyperplasia and papillary ductal hyperplasia. The epithelium may be atrophic or hyperplastic and occasionally may show a pseudoepitheliomatous hyperplasia.
Ulceration can occur.
Infrequently, chondroid or osseous metaplasia can develop within the mass. In addition, correct the denture, otherwise the lesion will recur. Either make a new denture or reline the old denture. Patients who wear dentures frequently believe that they no longer require care, and, under these circumstances, dentures lose their correct fit and become the source of irritation. With correction of the poorly fitting denture, prognosis is excellent.
