title: Monarticular erosive osteoarthritis: a possible source of confusion with infectious arthritis.
abstract: Although monarticular erosive osteoarthritis is uncommon, it is not rare. In our example, there was a monarticular presentation of cartilage destruction, soft tissue swelling, and linear periosteal bone apposition. Such bone apposition adjacent to affected joints is not uncommon in erosive osteoarthritis. However, when observed in the context of monarticular disease, particularly when accompanied by soft tissue swelling, it could easily be mistaken for an infectious arthritis.
