Spontaneous remission of Felty's syndrome.

The clinical course of a patient with Felty's syndrome is described. This patient was unusual because during a 3-year period of splenomegaly and leukopenia she did not develop repeated infections, leg ulcers, or other complications of Felty's syndrome. Then a spontaneous remission began. During the subsequent 6 years, neither symptoms nor signs of Felty's syndrome have recurred.
