[Thrombocytopenic purpura in infectious mononucleosis (author's transl)].

A patient with infectious mononucleosis (IM) and thrombocytopenic purpura is reported. Clinical symptoms were not suggestive and diagnosis was based on the presence of lymphomonocytic cells in peripheral blood and serologic study. Bone marrow aspirate showed characteristic features of an immunologic thrombopenia, though antiplatelet antibodies were not found. Literature on this subject is revised and pathogenic and therapeutic problems are discussed.
