Definition/Description[edit | edit source]

Felty syndrome (FS) is a rare rheumatic disorder that is typically distinguished by the following subsequent conditions: rheumatoid arthritis (RA), low white blood cell count (neutropenia), and an enlarged spleen (splenomegaly), and recurring infections. Cite error: Invalid <ref> tag; name cannot be a simple integer.

Use a descriptive titleFurthermore, it can be characterized by the triad of rheumatoid arthritis, severe extra-articular disease, and an unexplained neutropenia.


FS, a rare complication of RA, was first described by Dr. Augustus Felty in 1924. It is characterized by a triad of symptoms: seropositive RA with severe joint involvement, neutropenia, and splenomegaly. However, the triad is not required for diagnosis. Splenomegaly and severe joint involvement are not always present in some people with FS, and some people can even present with no symptoms. Neutropenia is the hallmark symptom of FS and is key for diagnosis. FS can be a potentially life-threatening, serious systemic condition due to its increased risk for infection during an immunosuppressed state of RA. Cite error: Invalid <ref> tag; name cannot be a simple integer.
