Abstract
Gingival fibromatosis is generally regarded as a disease that leads to an extensively diffuse and remarkable hyperplasia of the maxillo-mandibular gingiva.
Recently, we encountered a comparative rare case of gingival fiblomatosis accompanied by marked enlarging masses in the right maxillo-mandibular gingiva. The patient, a 21-yearold female, had been aware of a diffuse hyperplasia in right the maxillo-mandibular gingiva for about 2 years. As the lesion had increased remarkably as nodular masses, she was referred to our hospital.
The patient's parents were cousins. Except for her elder sister, there was no family history of gingival firomatosis. Thus, the influence of hereditary factors in our patient was obscure.
Based on clinical and histopathological findings, the unilateral remarkable phymatoid gingival hyperplasia was considered to be caused by gingival fibromatosis with inflammatory hypertrophy.
Under general anesthesia, gingivectomy was performed without extraction of teeth. The postoperative course was satisfactory.
After the operative wound had healed she was given instructions in tooth brushing. To date, 4 years and 6 months after operation there has been no occurrence.
