Surgical treatment of desmoplastic fibroma in the jaw using mandibular graft reconstruction – a case report

Resumo

: Considered a rare benign tumour of fibroblastic origin, desmoplastic fibroma is an injury with aggressive behaviour and local recurrence and unclear aetiology, although trauma and genetic factors are considered. The pathology may develop in the femur, radio, pelvis and tibia, and rarely affects the jaws, characterized as an injury of slow asymptomatic growth that may vary radiographically. The local aggressive resection is the treatment of choice. Objective: To report a case of a desmoplastic fibroma in the mandible, whose treatment was en bloc resection followed by reconstruction with mandibular graft. Case report: Female patient, 33 years old, Caucasian, with a bone lesion discovered in routine x-ray. Images showed hypodense image with discrete destruction of bone cortical, near teeth 36 and 37, with no involvement of the roots. The chosen treatment was en bloc resection followed by reconstruction with mandibular graft harvest from ramus. Conclusion: desmoplastic fibroma is a benign lesion that should be included in the differential diagnosis list of osteolytic lesions. A long-term follow up is required, considering the potential to recurrence.
