Abstract
We describe a 45-year-old man who developed a painful mass about his knee. Magnetic resonance imaging demonstrated a well defined lesion, and biopsy confirmed a diagnosis of pigmented villonodular synovitis. Our case exemplifies a primary synovial process presenting as a subcutaneous tumor. Such diagnostic possibilities, although rare, should be more widely known.
