Letter to the Editor: Pseudomalignant myositis ossificans mimicking osteosarcoma: a case report.

Radiographs and magnetic resonance images were not published for want of space. Magnetic resonance imaging is superior to computed tomography for detection of a soft tissue mass. Hence computed tomography was not considered in our preoperative investigations. The diagnosis of osteosarcoma was not made before the biopsy. Open biopsy was performed rather than fine-needle aspiratory cytology or needle biopsy, because the accuracy of the latter techniques varies between 65% and 80% in unsuspected soft tissue lesions.
