Gingival fibrous nodule--anomaly or pathology?

Three cases of a relatively common but rarely reported intraoral condition are described. Clinically, this condition appears as an asymptomatic, tumor-like nodule or nodules along the labial anterior mucogingival line and are characterized histologically by an accumulation of dense collagenous tissue. This entity represents a developmental condition and should be distinguished from reactive and neoplastic lesions. No treatment is necessary.
