title: A case of rheumatoid nodulosis successfully treated with surgery.
abstract: We report the case of a 76 year-old male with multiple subcutaneous nodules, but without joint symptoms or deformities, who was diagnosed histopathologically with rheumatoid nodulosis after resection of the nodules. Rheumatoid nodulosis is a disease characterized by multiple subcutaneous nodules that are histopathologically similar to rheumatoid nodules, a high titer of rheumatoid factor, and radiologically detectable cystic bone lesions, but with none or few of the systemic manifestations orjoint activity of rheumatoid arthritis (RA). It is considered to be a benign variant of RA. This rare disease must be considered when a case of multiple subcutaneous nodules is encountered, even in aged males withoutjoint symptoms or deformities.
