Parvovirus B19 can cause a wide range of cutaneous or extracutaneous d
iseases. There are three types of exanthemas, erythematous maculopapul
ous or vesicopapulous exanthema including erythema infectiosum, the le
ss common maculoerythematous exanthemas and purpural exanthemas includ
ing vascular, thrombocytopenic or non-vascular or non-thrombopenic for
ms such as le socks and gloves syndrome.Reports of other manifestation
s have been more sporadic: generalized livedo, polymorphous rash, lupu
s-like rash and Kawasaki syndromes. The presence of unusual presentati
ons and the risk of fetomaternal transmission are two reasons for bett
er understanding this virus.
