Infection with parvovirus B19 may result in a wide range of dermatologic manifestations. The specific skin findings include erythema infectiosum and papular purpuric "gloves-and-socks" syndrome. The nonspecific findings include reticular erythema, maculopapular eruptions, and petechiae and purpura, as well as other less frequently described findings. Associations with other dermatologic diseases, such as erythema multiforme and erythema nodosum, also have been described. A role in the pathogenesis of various collagen vascular disorders has been suggested and is under investigation. The diagnosis of infection rests on the typical clinical findings. Whenever parvovirus B19 infection is diagnosed, the physician must ensure that neither the patient nor his or her contacts is a member of certain vulnerable populations. In these populations, infection with parvovirus B19 may result in devastating complications. The vulnerable populations include those with hematologic disease, immunosuppressed patients, and pregnant women. Treatment of infection in the healthy immunocompetent individual is asymptomatic, and the acute infections typically resolve without complications.
