Central Odontogenic Fibroma: A Case Report
Central odontogenic fibroma is a rare benign odontogenic tumor, representing less than 1.5% of all odontogenic tumors. The tumor derives from mesenchymal tissue of dental origin, such as periodontal ligament, dental papilla, or dental follicle. Our case report is of a 52-year-old female, with a chief complaint of a bony hard swelling on her right gum. Panoramic and cone-beam CT imaging reveal a large, well-defined multilocular radiolucent lesion with wispy septa on the right posterior mandible, including numerous foci of irregular radiopaque masses within the lesion. Buccal and lingual bone expansion is seen. Biopsy confirmed central odontogenic fibroma, WHO type. Our case report was one of only three cases diagnosed as central odontogenic fibroma in a 5-year survey (2009-2013) of the Faculty of Dentistry, Chiang Mai University, and represented only 0.14% of 2,221 biopsy specimens. Simple enucleation of the lesion was performed under general anesthesia. A 5-months follow-up showed no recurrence of the lesion. In conclusion, our case study of central odontogenic fibroma in the mandible is a rare case found at our faculty. It was similar to previousreportedcasesfromthe literatures,inclinical, radiological and histological features
