A classic case of ITP in a woman presenting with spontaneous bruising.

Idiopathic thrombocytopenic purpura is an autoimmune disorder causing thrombocytopenia. The authors present the case of a patient who presented with spontaneous bruising. A complete blood cell count revealed the patient was severely thrombocytopenic with a platelet count of 4000. Further evaluation failed to reveal a cause for thrombocytopenia and the patient was subsequently diagnosed with idiopathic thrombocytopenic purpura.
