This case report describes a rare presentation of Ewing's sarcoma in the calcaneus successfully treated with preoperative chemotherapy and below knee amputation.
May support neoadjuvant chemotherapy and amputation in rare calcaneal Ewing sarcoma; leaves open need for larger series to guide practice.
Ewing's sarcoma is rarely foundoccurs in the bones of the hands and feet. We report a case of Ewing's sarcoma of the left calcaneus in a 15-year-old girl who complained of left heel pain and swelling. An open biopsy was performed and histological examination showed the proliferation of uniform small round cells. Immunohistochemical staining for CD99 showed diffuse strong positivity in the cytoplasmic membrane of the tumor cells. After preoperative chemotherapy, a below knee amputation was performed.
