Osteonecrosis Mandibular Extended to Bisphosphonates: A Very Rare Extensive Case.

After the first report of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in 2003, it has increased significantly since then. We report a very rare extensive case never seen before in our experience of bone exposure with necrosis reaching the mandibular inferior border. Although the treatment modalities are not yet established, most researchers have recommended conservative approaches. The surgery was to be as conservative as possible, with a resection of the mandibular range followed by reconstruction using titanium plate with space maintainer. The authors would like to share their approach, management, and awareness.

[Craniofacial adulthood rhabdomyosarcoma: a case with poor prognosis]. / Rhabdomyosarcome cranio-facial de l'adulte: un cas de mauvais pronostic.

Rhabdomyosarcoma is the more frequent mesenchymal tumor in children and in adolescents. It accounts for 60 -70% of mesenchymal tumors and approximately 5% of all solid tumors occurring at these ages. Almost half of rhabdomyosarcomas occur in the head and the neck. We report the case of a 20-year old patient with a new histological, aggressive temporo-parietal rhabdomyosarcoma.

Sarcomatoid Carcinoma of the Maxilla: A Case Report with Literature Review.

Sarcomatoid carcinoma is a very rare malignant and aggressive tumor that can involve the maxillary sinus. We report the case of a 46 y/o male who presented a tumor of the right maxillary sinus with extension to the right nasal cavity. The diagnosis of sarcomatoid carcinoma was set by histology and immunohistochemistry. The patient received concomitant cisplatin based chemoradiotherapy with no response after 3 months of treatment. He died 6 months later. Through the present case and the review of literature we discuss all aspects of this entity: clinical presentation, differential diagnoses, pathology, treatment and prognosis.
