[Cutaneous manifestations of parvovirus B19 infection].

Parvovirus B19 can cause a wide range of cutaneous or extracutaneous diseases. There are three types of exanthemas, erythematous maculopapulous or vesicopapulous exanthema including erythema infectiosum, the less common maculoerythematous exanthemas and purpural exanthemas including vascular, thrombocytopenic or non-vascular or non-thrombopenic forms such as le socks and gloves syndrome. Reports of other manifestations have been more sporadic: generalized livedo, polymorphous rash, lupus-like rash and Kawasaki syndromes. The presence of unusual presentations and the risk of fetomaternal transmission are two reasons for better understanding this virus.
