Peripheral odontogenic fibroma (POF, WHO-type) is a relatively rare benign tumor which shows sessile, firm, and exophytic gingival enlargement. Microscopically, a POF is a gingival lesion consisting of scattered and multiple islands of odontogenic epithelial strands and keratinized stratified squamous epithelium with long and thin rete pegs underlying fibrocellular connective tissue. A mature lesion of POF is clinically difficult to distinguish from pyogenic granuloma, due to their similar shapes and colors, and the fact that pyogenic granuloma is a frequently-occurring disease. Therefore, we report a case of POF in a 37-year-old female and compare it with pyogenic granuloma.
