Felty's syndrome is an uncommon but severe extra-articular manifestation of rheumatoid arthritis. Felty's syndrome is characterized by the triad of rheumatoid arthritis, neutropenia, and splenomegaly. The lifetime risk of Felty's syndrome for a rheumatoid arthritis patient is less than 1%. We present a case which is a classical presentation of Felty's syndrome with the triad of RA, neutropenia and splenomegaly. We present a case of 51-yearold woman on chronic RA treatment who presented with cellulitis. The work up showed splenomegaly and neutropenia which support Felty's syndrome diagnosis. Patients with Rheumatoid arthritis (RA), who developed neutropenia and splenomegaly, should be suspected of developing Felty's syndrome as a complication of Rheumatoid arthritis.
