PERIPHERAL OSSIFYING FIBROMA OF ORAL CAVITY: HISTOPATHOLOGIC DIFFERENTIAL DIAGNOSES
AbstractPeripheral ossifying fibroma is a benign neoplasm that usually develops from gingiva, presenting as anexophytic smooth surfaced pink or red nodular mass that is sessile or is less frequently seen on apedicle. From the Indian perspective, it is usually noticed in 5th–6th decades of life with femalepredilection. Microscopically, the tumour shows stratified squamous epithelium and highly cellularfibrous stroma, sparse endothelial proliferation with fibroblasts and dystrophic calcifications. It has tobe differentiated histopathologically from pyogenic granuloma, fibroma, peripheral giant cellgranuloma, peripheral odontogenic fibroma and fibrous hyperplasia. A case of peripheral ossifyingfibroma of maxillary gingiva in a 55-year-old Indian woman is reported.Keywords: Peripheral ossifying fibroma, oral cavity, gingival growth, histopathologic differentialdiagnosis
