Peripheral Fibro-osseous Lesion: An Institutional Study of 38 Cases.

Background: The term "peripheral fibro-osseous lesion (PFOL)" is used relatively for common gingival lesions characterized histologically by hypercellular connective tissue showing either new bone-like formations or cementum-like substance and rarely dystrophic calcifications. These lesions are closely related to the other fibro-osseous lesions such as cemental periapical dysplasia, fibrous dysplasia, and other calcifying odontogenic cysts and tumors. The etiology is unknown, but certain authors suggest plaque, dental calculus, and ill-fitting dentures which might be the irritating agents causing irritation to the periodontal ligament which leads to such reactive growth.

Oral Mucous Membrane Pemphigoid.

Pemphigoid is a group of rare autoimmune diseases affecting the skin and the mucous membrane in which the autoantibodies are directed against the basement membrane zone target antigens causing subepithelial blistering. Oral health professionals are usually the first to identify as more than 90% of cases show oral lesions initially. A lack of diagnostic criteria can lead to misdiagnosis and delay in treatment.

A novel mucocele: Myxoglobulosis.

Oral extravasation mucoceles are among the most widely recognized submucosal lesions which are usually a result of trauma involving salivary glands and their ducts. This paper reports a case of a 40-year-old female patient with a chief complaint of a painless swelling on the lower lip since 6 months. Upon a provisional diagnosis of mucocele, surgical excision was carried out.
