Abstract
We report the association of myasthenia gravis (MG) and autoimmune thrombocytopenic purpura (AITP) in a 13-year-old girl. The co-existence of these autoimmune diseases is rare in adults and, to our knowledge, never described in children. In our patient thymectomy had a therapeutic effect on both MG and AITP, suggesting a altered T-cell function as a pathogenic factor of major importance in both affections.
