Felty syndrome (FS) is an uncommon extra-articular manifestation of seropositive rheumatoid arthritis (RA) characterized by RA, neutropenia, and splenomegaly. Felty syndrome was first described in 1924 at Johns Hopkins hospital by the American physician, Augustus Felty. He described five unusual cases with common features of chronic arthritis of about four years duration, splenomegaly, and striking leukopenia. The term was first used by Hanrahan and Miller in 1932 when they described the beneficial effect of splenectomy in a patient with features similar to the five cases reported by Felty. While Felty syndrome characteristically demonstrates chronic arthritis, splenomegaly, and neutropenia; completion of the triad is not necessary for the diagnosis. Neutropenia, however, is a hallmark feature of the disease and cannot be absent.
