 AB    We report a 28-year-old Japanese with Klinefelter's syndrome who
       developed mixed connective disease (MCTD) and Sjogren syndrome.
       Previously being well, he presented with Raynaud's phenomenon, dry eye,
       fever and polyarthralgia. Clinical examinations revealed anti-nRNP
       autoantibody, leukopenia and lung fibrosis. Then he was found to have
       Klinefelter's syndrome. Flow cytometric analysis showed a relative
       increase of peripheral CD8+ T lymphocytes carrying either HLA-DR or
       CD57. Lymphocyte IL-2 production induced in vitro by concanavalin A was
       decreased. Such T cell abnormalities may be implicated in the
       development of autoimmune disease in Klinefelter's syndrome.
