Abstract
A case of peripheral ameloblastoma, occurred in the lingual gingiva of 3 4 of a 37-year-old female, is presented here. The patient noticed a tumor with neither symptoms nor tendency of growth about 6 months before the resection at our department. The tumor was hemi-spherical in shape, measuring 1.2×1.2×0.5mm, elastic hard in consistency, and covered with a normal mucosa. Dental x-ray films revealed radio-opacity with a focal radio-rucent area beneath the tumor. The resection of tumor was carried out at a dental clinic with a clinical diagnosis of benign tumor. Pathologically, it was diagnosed as ameloblastoma and tumor cells were observed at the surgical edge. Thereafter, the patient was referred to our department and underwent the en bloc resection of the alveolar bone of 3 4 5 area. The histology of the resected bone showed an invasion of tumor cells in the periodontal ligament of 4.
The postoperative course has shown no evidence of recurrence for about 11 months.
