The case of a patient with a second recurrence of a chondrosarcoma of the pelvis and pubic symphysis is presented, in order to show the difficulties of the surgical treatment and the long course of the tumor. A 56-year-old woman having already been operated upon twice within two decades, presented with a large, mass of the pubic symphysis, extending into the left proximal thigh. Preoperative imaging revealed a large tumor occupying the pubic symphysis and the pubic bones up to the ischial tuberosities, extending into the soft tissues of the inner surface of the left thigh and displacing the urinary bladder, the urethra and the vagina. Intraoperatively, a radical excision of the tumor was performed, including removal of the osseous substrate of the anterior pelvis. The anterior abdominal wall was supported with a special synthetic mesh secured on the osseous stumps in order to prevent visceral herniation. Histological examination showed grade I to II chondrosarcoma, while the patient's postoperative course was uncomplicated. At the latest follow-up two years postoperatively, the patient is pain-free and ambulatory with no signs of tumor recurrence, genitourinary complications or visceral herniation.
