title: The forgotten nodule: complications of sacral nodules in rheumatoid arthritis.
abstract: Nodules commonly occur in rheumatoid arthritis and occasionally give rise to complications. The sacral nodule is easily missed and may ulcerate to produce extensive sacral sores which may lead to serious and even fatal complications in patients with rheumatoid arthritis. Seven cases are reported which illustrate some of these features.
