[Incomplete Felty syndrome with manifestation of arthritis following a long-standing course of the disease].

A 62-year-old female patient with splenomegaly, severe granulocytopenia, recurrent infections and negative rheumatoid factor test initially had no clinical evidence of rheumatoid arthritis. Leucopenia responded to splenectomy and did not recur during 7 years follow-up. Symmetrical metacarpophalangeal joint-swelling developed 9 months after 7 years of radiographic destruction. This case emphasizes that arthritis may occasionally be a late and minor manifestation of Felty's syndrome.
