Verrucosis of hands and feet in a patient with combined immune deficiency.

Abstract

In immunocompromised patients, warts occur frequently and can be extensive. We describe a 24-year-old patient with severe therapy-resistant warts. In addition to human papillomavirus infection, he had chronic sinusitis, candidiasis, and atopic dermatitis. Anergy to delayed-type hypersensitivity skin test reaction, significant CD4 lymphopenia, and diminished in vitro T-cell proliferative response and interferon-gamma production indicated a deficiency of cellular immunity. Extremely low concentrations of serum IgM and IgG2 and a severe deficiency of in vitro IgM production pointed also to a humoral immunodeficiency syndrome. This case represents a combination of cellular and humoral immunodeficiencies that has not been previously described in association with warts.
