[Disseminated tuberculosis and profound thrombopenia]. / Tuberculose disséminée et thrombopénie profonde.

Thrombocytopenia within the context of disseminated tuberculosis can lead to complications requiring rapid treatment. Although the origin is generally central, thrombocytopenia can arise from an immune disorder. We hereby report a case of disseminated tuberculosis associated with thrombocytopenia, which required, in addition to antituberculosis therapy initiated before bacteriological proof, corticosteroid treatment and multiple platelet transfusions. The discovery of anti-platelet antibodies along with the success of immunomodulator therapy confirmed the auto-immune origin of this thrombocytopenia.
