An association between idiopathic thrombocytopenic purpura(ITP) and hyperthyroidism
has been reported since 1931, but the reports of typical antiplatelet-antibody-positive
ITP associated Graves' disease are rare in Korea. We recently experienced a patient
who presented with antiplatelet-antibody-positive ITP accompanied with Graves' disease.
On admission, she complained of epistaxis, petechiae, menorrhagia, palpitation, and
weight loss. The platelet count was 42,000¡¿106/L, T3RIA 300,06ng/dL,
thyroxine 15.13ug/dL and TSH below 0.29ug/dL.
Prednisolone and propylthiouracil were given to the patient with improvement of the
symtoms and improvement of thrombocytopenia.
