RESUMO
Brucellosis is a multisystem disease usually presenting with a wide spectrum of clinical and laboratory manifestations. Hemtological manifestations are many and may include anemia, thrombocytopenia and / or leucopenia. In rare cases, thrombocytopenia can be severe and may result in bleeding into the skin and other mucosal sites. Prompt recognition of this complication and aggressive therapy are essential, since the mortality associated with bleeding into the central nervous system is considerable. In this short case report, we present a young patient with hematuria and thrombocytopenia associated with acute brucellosis. Thrombocytopenic purpura in this case did not respond well to high-dose intravenous immunoglobulin; however, treating the underlying acute infectious process resulted in a dramatic clinical and hematological improvement
