(OBQ12.153)
A 33-year-old motorcyclist is involved in a motor vehicle accident and sustains a Grade III open fracture of his tibia that is treated surgically. Over the next 35 years, he undergoes multiple debridements for a persistently draining wound. Over the last year, he has noticed "tissue growing out of the wound" and a malodorous smell. A photograph of the wound and a recent radiograph are seen in Figure A. A biopsy of the mass is shown in Figures B, and C. What is the most likely pathologic process?
