General Discussion

Felty syndrome is usually described as associated with or a complication of rheumatoid arthritis. This disorder is generally defined by the presence of three conditions: rheumatoid arthritis (RA), an enlarged spleen (spenomelgaly) and a low white blood cell count (neutropenia). The presence of RA gives rise to painful, stiff and swollen joints. A low white blood cell count, especially when accompanied by an abnormally large spleen, leads to a greater chance for infections. Other symptoms associated with Felty syndrome may include fatigue, fever, weight loss, and/or discoloration of patches of skin (brown pigmentation). The exact cause of Felty syndrome is unknown. It is believed to be an autoimmune disorder that may be genetically transmitted as an autosomal dominant trait.
