title: Giant desmoplastic fibroma in the anterior zone of the maxilla.
abstract: Desmoplastic fibroma (DF) is a rare intraosseous benign neoplasm that represents less than 1% of the osseous tumors. This lesion can be locally aggressive, and the rate of recurrence is frequently high.A 34-year-old male patient was referred to our clinic presenting a tumor in the anterior zone of the maxilla. The oral examination revealed a hard and lobulated tumor, affecting teeth 13 to 26. The radiographic examination, orthopantomography, and computed tomography revealed a radiolucent, multilocular, well-defined image, which extended from tooth 13 to the mesial root of tooth 26, provoking marked expansion, thinning, and perforation of the buccal and palatal cortical plates. A provisional diagnosis of aggressive odontogenic tumor was made, and block resection of the tumor was carried out. Intraoperatively, the tumor was lobulated, composed of a homogenous fibrous tissue, hard, and white-yellowish. The histologic analysis leads to a diagnosis of DF.Desmoplastic fibroma of the oral cavity is a rare benign intraosseous tumor, especially when it involves the upper maxilla and the anterior region. The main clinical and pathologic differential diagnosis in our case was central odontogenic fibroma. The most suitable treatment option for DF of the oral cavity is a controversial issue, but block resection is the therapy reporting a lower recurrence. Finally, an interesting feature of this intraosseous neoplasm, if located in the oral cavity, refers to the different clinical pattern that might present depending on location.
