[Hairy cell leukemia].

Clinical experiences on seven patients suffering from hairy cell leukaemia are presented. The disease was most often identified at age above 50 and was more frequent in men. Splenomegaly and infiltration of bone marrow or spleen with tartrat resistant acid phosphatase positive lymphoid cells were detected in all cases. Splenectomy resulted complete clinical remission in six and partial remission in one patient. Two patients have died. The mean survival time is five years. The surviving patients are in good clinical remission.
