Abstract
Ewing's sarcoma (EWS) is the second most common primary bone tumor seen in children
and adolescents, first being osteosarcoma. Skull lesions are seen in 6 to 9% of cases.
The tumor tends to reside most frequently on frontal and parietal bones. In the literature,
majority of papers on calvarial EWS present cases with intracranial involvement; extracranial
extension is reported in only eight cases. The case that we are presenting in this
report is a 23-year-old male patient with multiple infiltrations in femur, costal
bones, and calvarium which had been diagnosed radiologically and histopathologically
as EWS. The calvarial metastasis had reached a very huge size with dimensions of approximately
7.5 × 7.5 × 9.5 cm and was successfully excised totally. Twelve months of follow-up
revealed no recurrence in the surgical site showing that total removal of giant cranial
EWS may improve morbidity of these patients.
