Odontogenic tumor, fibroma, differential diagnosisAbstract
The odontogenic fibroma is a rare odontogenic tumor of mesodermal origin, originating from the dental follicle, periodontal
ligament and/or the dental papilla. 1 Different studies reported a high variability in the incidence rate, ranging from 3% to
23% of all odontogenic tumors. 2, 3 The histopathological features show the odontogenic epithelial structures that mimic
those observed in ameloblastoma biopsy and also cell stroma fragments. The clinical and radiological features are similar
to other odontogenic and non odontogenic tumors. In the case reported, a young patient showed an increased volume
at the level of inferior retromolar mucosa that radiologically involves expansion of the buccal and palatal bone table at
the right mandibular angle. Morphological characteristics, together with clinical, imaging and histopathological findings,
confirmed that the tumor was a central odontogenic fibroma. Rare benign odontogenic tumors can be distinguished from
other odontogenic/nonodontogenic neoplasms and malignant tumors through a differential histopathological diagnosis on
which the treatment to be performed depends.
