Peripheral ossifying fibroma: A case report

Abstract

Localized gingival growths are one of the most frequently encountered lesions in the oral cavity, which are considered to be reactive rather than neoplastic. Different lesions with similar clinical presentation make it difficult to arrive at a correct diagnosis. These lesions include pyogenic granuloma, irritation fibroma, peripheral giant cell granuloma, peripheral ossifying fibroma (POF). Among these lesions, an infrequently occurring gingival lesion is the POF. Considerable confusion has prevailed in the nomenclature of POF due to its variable histopathologic features. This is a case presentation of a 30-year-old female with gingival overgrowth in the mandibular left canine-premolar region. Clinically, the lesion was asymptomatic, firm, pale pinkish and sessile. Surgical excision of the lesion was done followed by histopathologic confirmation with emphasis on the clinical aspect. Given the rate of recurrence for POF being 8-20%, close post-operative follow-up is required.

Management of residual mucogingival defect resulting from the excision of recurrent peripheral ossifying fibroma by periodontal plastic surgical procedure

“…Chronic inflammation may irritate the periosteum, and periodontal membrane cause metaplasia of connective tissue and resultant initiation of formation of bone or dystrophic calcification. [ 6 ]…”

“…report;[ 12 ] used soft tissue grafting immediately after excision of gingival reactive lesion whereas Barot et al . [ 6 ] reported no reoccurrence after 6 months of complete excision of POF.…”

“…[ 1 2 ] Prevalence of the POF among females is higher[ 3 ] and often occurs in 2-3 decades of life. [ 4 ] Though the etiopathogenesis is unclear, it is supposed to be arising from the periodontal ligament[ 5 6 ] and is frequently allied with local irritants factors such as dental plaque, calculus, microorganism, poor restoration, etc. [ 5 7 8 ] Occasionally, large POF lesions exhibit foci of calcification which elicit radio opaque changes on radiograph but not always.…”

Structure, Localization of Tumor and Tumorlike Diseases of the Oral Cavity

“…При гистологическом исследовании такой гиперплазии определяют пери-ферическую оссифицирующую фиброму (оссифи-цирующий фиброзный эпулис), периферическую фиброму (фиброзный эпулис), периферическую гигантоклеточную гранулему (гигантоклеточный эпулис) [7,12]. В современной литературе при-сутствует значительная путаница в номенклатуре разных форм гингивальных гиперпластических доброкачественных изменений [7]. Разные формы эпулиса диагностируются в 15,8-61,1% случаев [6,12,16].…”

Peripheral ossifying fibroma: A rare case affecting maxillary region

“…Focal gingival enlargements are quite frequent lesions in the oral cavity amounting to almost 3.1% of all oral tumors and for 9.6% of gingival lesions. [ 1 ] In 1992, the World Health Organization classification about this kind of focal overgrowth had tapered toward one universal term “Peripheral Cemento-Ossifying Fibroma.” These lesions histopathologically have fibrous stroma with varying amounts of mineralized materials. [ 2 ] We, in our case report prefer to call it as peripheral ossifying fibroma (POF).…”
