Introduction Central odontogenic fibroma (COF) is a rare, benign, slow-growing intraosseous odontogenic tumor, and accounts for 0.1% of all odontogenic tumors. It is often confused with other entities, such as keratocysts, ameloblastomas, and odontogenic myxomas. Complete enucleation followed by curettage is the treatment of choice for COF to ensure the lowest possible chance of recurrence. Case presentation We report the case of a young Caucasian woman with COF that went undiagnosed for several years despite repeated radiologic examinations. Finally, a massive tumor was surgically removed and the wound was curetted. The specimen was histologically confirmed to be a COF. The patient remains under regular follow-up, and thus far there have been no clinical or radiologic signs of recurrence. Discussion This rare case of COF, which was documented over a period of 20 years, has helped us to describe the features of this tumor. It also confirms that adequate surgical treatment can lead to impressive bone regeneration in healthy individuals, as evident from the radiologic findings acquired before, during, and after enucleation of the COF in our patient. Our findings also confirm the view that COF has a favorable prognosis regardless of its final size. Conclusion Early diagnosis is key to successful treatment of COF. The slow but steady increase in the size of a COF with no accompanying symptoms has not been reported previously. To our knowledge, this is the only documented case of a COF that has been under continuous radiologic observation for over 20 years.
