This 55-year-old Hispanic woman with a history of Wegener's granulomatosis presented with a nosebleed. She had bruising on her arms and legs over the past 1.5 months and bleeding gums. Lab work showed thrombocytopenia. A bone marrow biopsy showed orderly trilineage maturation with adequate megakaryocytes. She was diagnosed with idiopathic thrombocytopenic purpura (ITP) rather than thrombocytopenia related to her Wegener's. Treatment options for ITP include corticosteroids, IVIG, anti-D immunoglobulin, and splenectomy.
