ABSTRACT
Reconstruction of the mandible with a free fibular graft is one of the most common treatment choices following tumor resection. But as the graft is often vertically deficient, pathological fracture may occur because of occlusal forces after prosthetic rehabilitation. Distraction osteogenesis can be a good choice for the repair of the fibular flap. In this report, a case of fractured fibula flap after 7 years, rehabilitated with a posteriorly directed vertical distractor, will be presented.
ABSTRACT
Eosinophilic granuloma is the most common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. Early clinical signs can occur in the mandible and can cause extensive destruction of the periodontal tissues. Pathologic fracture is an unusual finding. A case of misdiagnosed eosinophilic granuloma in a 45-year-old man treated with free fibula flap and implant-supported overdenture prosthesis is reported. Free fibula flap with dental implants is a safe and reliable method for comprehensive functional and aesthetic mandibular defect reconstruction.

Fibrosarcoma of the paranasal sinuses is extremely rare pathology and there is limited report in the literature. We report synchronous presentation of maxillary sinus fibrosarcoma and gemistocytic astrocytoma which is, to our knowledge, unique in the literature. Both tumors metastases to other organ rarely and the metastatic spread of gemistocytic astrocytoma to fibrosarcoma or vice versa have also not been reported in the literature yet. This report discusses the clinical course of the disease, outcome of the treatment approach and survival as well as an unusual occurrence of leukocytoclastic vasculitis during the course of radiotherapy in such unusual presentation.
