    General Discussion

    Felty Syndrome is a rare form of Rheumatoid Arthritis, a disorder characterized by painful, stiff, and swollen joints. Major symptoms and physical findings of Felty Syndrome include an unusually large spleen (splenomegaly) and abnormally low levels of certain white blood cells (neutophils [neutropenia]). As a result of neutropenia, affected individuals may have an increased susceptibility to certain 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.
