CALCIFYING HAEMATOMA MIMICKING A SOFT TISSUE SARCOMA AND MYOSITIS OSSIFICANS

We describe a case of calcifying haematoma in a 78-year-old war veteran with a mass in his right lower leg. The likely differential diagnosis of myositis ossificans and soft tissue sarcoma was worked up. We discuss some of the difficulties of diagnosis despite having computed tomography and magnetic resonance imaging examinations and the unexpected final diagnosis of calcifying haematoma that was made on incisional biopsy.
