Inclusion body myositis in association with rheumatoid arthritis.
We describe 2 patients with rheumatoid arthritis (RA) and inclusion body myositis (IBM). Examination and laboratory tests including muscle biopsy with frozen section and electron microscopy were performed. Both patients fulfilled diagnostic criteria for IBM, which is increasingly recognized in association with autoimmune disease. A high index of suspicion and early thorough investigation are required to diagnose IBM in patients with RA.
