[Cytogenic chorion sarcoma: clinical and radiological features].

Endometrial stromal sarcomas are rare tumors affecting young women. Diagnosis is most often made after surgery. We here report the case of a 22-year-old girl admitted with pelvic pain associated with metrorrhagias. Imaging objectified heterogeneous uterine mass. The diagnosis of atypical fibroid was suspected. Definitive diagnosis was based on histological examination of the surgical specimen.
