Felty's syndrome refers to a severe form of rheumatoid arthritis (RA) that often presents clinically with splenomegaly and neutropenia. This triad of features do not have to be complete in all patients, but neutropenia (absolute neutrophil count of less than 1500/mm3) must be present for the diagnosis. Felty's syndrome was first described by Dr Augustus Felty in 1924.
