[A case of benign chondroblastoma of the iliac wing treated by extensive exeresis and reconstruction with methylmethacrylate].

Complete remission can be achieved by extensive surgical exeresis in patients with benign chondroblastoma of the iliac wing despite the reputation of these tumors for aggressive behavior. The case of a 28-year-old male treated with extensive surgery and acrylic cement reconstruction is reported. After seven years follow-up, the functional result is satisfactory and there is no evidence of local recurrence. Use of cement obviated the need for bone grafting. However, subsequent removal of the cement proved necessary because of skin intolerance. Data from a review of the literature confirmed that iliac chondroblastoma carries a poor prognosis, mainly because of the potential for mechanical complications. The cases of malignant transformation reported occurred after radiotherapy. In the authors' opinion, extensive surgical exeresis performed as early as possible is the treatment of choice.
