Ewing's sarcoma is uncommon malignancy of childhood, frequently involving the mandible. The occurrence in maxilla is rare. It is histopathologically characterized by sheets of round cells positive for CD99. Although the prognosis is poor but early diagnosis and long term follow up can improve the survival. This article presents a rare case of Ewing's sarcoma of maxilla in a 15 year old male patient showing excessive fibro-osseous response which is not a frequent presentation. A retrospective analysis of cases of Ewings sarcoma of maxilla published in the English litreture is reviewed. In our case, diagnosis was confirmed by immunohistochemistry where sheets of round tumor cells were positive for CD 99. Ewings sarcoma of maxilla is a rare and aggressive tumor. Hence early diagnosis, combined therapy and long term follow up is suggested in such cases.

Rhabdomyosarcoma of the Maxilla.

Rhabdomyosarcoma is the most common soft tissue sarcoma in children but is less frequent in adults, with the head and neck region as primary site. Magnetic resonance imaging (MRI) is the preferred diagnostic imaging tool, though its imaging characteristics are relatively non‑specific and overlap with other soft tissue sarcomas. The prognosis of rhabdomyosarcoma depends on the primary tumour site and size, with parameningeal head and neck localisations having a less favourable prognosis due to the higher risk of spread.

Background: Over the past few decades, fibular grafts have been widely utilized across 86 countries and regions globally for surgical reconstruction of various anatomical sites, including the mandible, upper extremities, lower extremities, spine, and in phalloplasty procedures. The present study aims to systematically investigate the developmental trajectory of fibular graft and identify research priorities for surgeons.
Methods: A bibliometric analysis was conducted by searching the Web of Science Core Collection on April 12, 2024, for articles published between 2004 and 2023 on fibular grafting, using the query TS = ("graft" OR "transfer" OR "flap") AND TS = ("fibular").

Introduction: Sarcomas of the head and neck region account for less than 10% of soft tissue sarcomas, and comprise less than 1% of head and neck malignancies. Approximately 80% of sarcomas arise from soft tissue, with the remaining originating from bone or cartilage. Head and neck sarcomas typically occur more frequently in men.

Article Synopsis
- Fibrous dysplasia (FD) is a nonheritable genetic condition that causes abnormal bone growth, leading to benign lesions that can sometimes become malignant, as exemplified in a case of a 61-year-old man with painful craniofacial FD.
- The patient presented with a rapidly growing mass in the skull, which MRI revealed as an extensive dysplastic mass causing significant pressure on the brain; he underwent surgery to remove the mass.
- Post-surgery pathology confirmed it as a high-grade undifferentiated pleomorphic sarcoma, leading to further treatment with chemotherapy, though the effectiveness of such treatment remains debated.
