Hereditary gingival fibromatosis is an uncommon congenital anomaly of undetermined etiology, the condition is manifested as a dense, diffuse, smooth or nodular overgrowth of the gingival tissue, usually begins with the eruption of the permanent incisors. However, it may happen as early as the eruption of the deciduous teeth. The case, a 30 years old woman with normal stature, visited our dental clinic because of "overgrown gum" which greatly affected mastication and appearance. A review of her past medical history revealed no relevant diseases. Oral examination showed gross fibrous enlargement of gingival without inflammation or swelling. Her father, two sisters and one daughter also suffered from this disease. Microscopically, there is a obvious increase in the amount of connective tissue that is relatively avascular and consists of densely arranged collagen bundles and numerous fibroblasts. The surface epithelium is thickened and acanthotic with elongated rete pegs. Gingivectomy with flap operation were performed to correct the gingival overgrowth. After periodontal treatment, two fixed partial dentures were constructed to replace the missing right upper and lower first molars. One year after operation, no obvious recurrence was noted clinically.
