Cytomegalovirus-Induced Thrombocytopenia in an Immunocompetent Child

Although thrombocytopenia has been commonly observed in patients with congenital cytomegalovirus infection, it has rarely been reported after cytomegalovirus infection in immunocompetent children or adults. In the literature, approximately 20 cases of cytomegalovirus-correlated thrombocytopenia are reported. Most of these patients were treated with corticosteroids, but some recent experiences have recommend the use of intravenous immunoglobulin, particularly in cases of severe bleeding or evidence of purpura and petechiae or when the platelet level is very low (<20 × 109/L). We report a case of an immunocompetent child with acquired cytomegalovirus infection presenting with purpura and thrombocytopenia in the absence of other symptoms and treated with intravenous immunoglobulin.
