Case Report (n=1)
This case report describes the first known instance of congenital extraosseous Ewing sarcoma presenting as a scalp mass.
Alerts clinicians to congenital EES in neonatal masses; leaves open standardized diagnostic and therapeutic approaches.
Ewing sarcoma is a locally aggressive, highly malignant tumor most commonly seen in the skeletal system. The "Ewing family of tumors" also includes other tissue types that are not common, such as soft tissue origin classified as extraosseous Ewing sarcoma (EES) or primitive neuroendocrine origin. Age of onset most often occurs within the first 2 decades of life. Congenital presentation of EES is exceedingly rare. We report the first described case to our knowledge of congenital EES originating from the scalp.
