Reconstruction of the abdominal wall after radical resection of pelvic osteochondroma

A 47-year-old female patient presented with a mass in the right hip. A CT scan showed an exophytic tumor with polylobulated edges measuring 68 × 65 × 70 mm on the external side of the right iliac wing (Fig. 1). The pathology report of the biopsy indicated differentiated cartilage proliferation suggestive of osteochondroma. Radical en bloc resection of the tumor including abdominal wall was performed, as well as reconstruction with titanized mesh with bone anchorage (titanium harpoons) and coverage with a fascia graft of the tensor fascia lata muscle (Fig. 2). The patient recovered well and was discharged on the fourth postoperative day without complications.
