[Joint manifestations in chronic T-cell lymphocytosis and neutropenia].

The authors report the case of a patient suffering from chronic T-cell lymphocytosis and neutropenia (CTLN), detected from seropositive rheumatoid arthritis with attacks of fever. The distinctive features of CTLN, isolated from other forms of chronic T-cell lymphoid leukemias, are recalled. The frequency and nature of joint signs found during this new hematologic entity are described.
