Abstract :
[en] Simultaneous reactivation of distinct Herpesviridae with development of clinical manifestations is exceptional. We report a 48-year-old woman suffering from idiopathic thrombocytopenic purpura. As the disease remained refractory to corticosteroids, immunoglobulins and splenectomy, a cure of vinblastine was administered. An atypical stomatitis developed few days later. Immunohistochemistry on a Tzanck smear and a biopsy evidenced a Herpes simplex virus type 1 (HSV-1) infection. The patient presented simultaneously a single necrotic lesion on the abdomen. Immunohistochemistry on a skin biopsy revealed the presence of the varicella-zoster virus (VZV) gE, gB and IE63 proteins. Intravenous aciclovir was initiated. The present case of simultaneous clinical infections by HSV-I and VZV underlines the importance of complementary viral identification testing in the event of unusual clinical presentations.
