[A 44 year old patient presenting with Ewing's sarcoma of the big toe].

We present the case of a patient with osseous Ewing's sarcoma of the big toe occurring during the healing process after a fracture of the little toe, which significantly delayed diagnosis, despite striking findings on imaging. We subsequently performed further diagnostics, neoadjuvant chemotherapy, tumor resection in the form of a resection of the first ray, and adjuvant chemotherapy. This case shows that the occurrence of a secondary disease should always be considered in untypical courses of healing.
