Two unusual hematologic presentations of tuberculosis.

Tuberculosis (TB), a common health problem in developing countries, is a specific multi-systemic infection that can lead protean manifestations in any organ system. Anemia and leukocytosis are the most frequent hematological findings at presentation and during the long clinical course of the disease. Coombs -positive hemolytic anemia and immune thrombocytopenic purpura (ITP) are exceedingly rare and life-threatening complications of TB. We report two patients with Coombs -positive hemolytic anemia and ITP that responded well to antituberculosis therapy.
