Abstract
Extraskeletal Ewing¡¯s sarcoma has been recognized as being histologically indistinguishable from Ewing¡¯s sarcoma
of bone. Histopathologically, Ewing¡¯s sarcoma consists of solid sheets of small round cells with vesicular nuclei and
scant cytoplasm, and the cells are arranged in irregular masses separated by strands of fibrous tissue. Extraskeletal
Ewing¡¯s sarcoma may arise virtually anywhere, but it is most common in the deep soft tissues of the extremities.
We report here on a 27-year-old woman with cutaneous extraskeletal Ewing¡¯s sarcoma. She presented with a
subcutaneous tumor of the right upper arm, and this was without osseous involvement. The patient underwent wide
local excision and she received chemotherapy with vincristine, cyclophosphamide, etoposide and ifosfamide. There
has been no evidence of recurrence or metastasis during 16 months of follow up.
