[CIC-rearranged sarcoma: a case report and literature review].

CIC -rearranged sarcoma is a rare and extremely aggressive tumor that occurs mainly in soft tissues. Despite the fact that identification of a characteristic genetic rearrangement is necessary to verify the diagnosis, in most cases, the correct diagnosis can be made by comparing histological signs and a characteristic immunophenotype, which greatly speeds up the diagnosis. The article describes a case of CIC- rearranged sarcoma in a 14-year girl with the successful application of the CWS-2009 treatment protocol.
