A 17-year-old girl presented with a 3-day history of epistaxis, vaginal bleeding and petechiae over the lower extremities. The patient had been feeling unwell with productive cough, fever, chills, poor appetite and weight loss for 2 months. Laboratory findings revealed anemia and thrombocytopenia, whereas bone marrow examination was unremarkable. She was diagnosed as having idiopathic thrombocytopenic purpura (ITP) in association with active tuberculosis (TB). The patient was treated with intravenous immunoglobulin (IVIg) and corticosteroid along with anti-TB drugs. During the follow-up period there was no recurrence of thrombocytopenia or TB. It is important to consider TB in the differential diagnosis of ITP, particularly in high TB-burden areas.
