Desmoplastic Fibroma of the Maxilla: A Report of a Rare Case.

Desmoplastic fibroma (DF) is an uncommon benign tumor of bone that is notable for its locally destructive nature and frequent recurrence. The lesion originates within the osseous tissue and most often affects the mandible, pelvic girdle, and long bones; involvement of the maxilla is rare. An 18-year-old female patient presented with a slowly developing lesion in the right maxillary premolar area. Clinical examination supported by radiographic findings demonstrated an intraosseous pathology, and histopathological evaluation confirmed the diagnosis of desmoplastic fibroma. Although benign, this tumor exhibits aggressive local growth, highlighting the importance of prompt diagnosis and definitive surgical treatment, particularly in rare maxillary cases, to reduce the risk of functional impairment and esthetic deformity.
