Acquired epidermodysplasia verruciformis in a child with the human immunodeficiency virus.

Epidermodysplasia verruciformis (EDV) is a rare genodermatosis characterized by susceptibility to human papilloma virus (HPV) infection. An acquired form of EDV has been described in the setting of immunosuppression, including in patients with the human immunodeficiency virus (HIV). We present the case of an HIV-positive, adopted Haitian boy who presented with EDV.

Exogenous immunoglobulin downregulates T-cell receptor signaling and cytokine production.

Intravenous immune globulin (IVIG), a polyvalent solution of pooled human immunoglobulin, is a potent immunomodulating agent. It is currently approved to treat autoimmune diseases, including idiopathic thrombocytopenia purpura, autoimmune hemolytic anemia, and Kawasaki disease. The basis of IVIG's immunomodulatory properties is not entirely understood.
