Description: This lesion appears as a mass of tissue arising from the gingiva adjacent to teeth or between teeth. It favors children and young adults. Those arising between teeth may separate the teeth and produce pressure resorption of the interdental bone. It's not unusual to see a saddle lesion straddling the ridge with a labial and linguallobe. Color is normal or slightly red. Histologically the bulk of this lesion is moderately cellular fibrous connective tissue frequently containing foci of bone, cementum, or dystrophic calcification. When inflammation is present, plasma cells frequently predominate.
Etiology: Unknown
Treatment: Excision. They may recur. Extraction of the adjacent teeth is seldom necessary.
Prognosis: Good
Differential diagnosis: Peripheral fibroma bears a great resemblance to pyogenic granuloma and peripheral giant cell granuloma. Histologic examination may be necessary to distinguish between them.
