[Visceral Larva Migrans: A pediatric case of atypical presentation with cutaneous vasculitis in the province of Buenos Aires, Argentina].

Toxocariosis is a parasitic disease caused by the larvae from genus Toxocara sp. There are two classic syndromes described for this entity: visceral larva migrans and ocular larva migrans, depending on larvae localization. Human being behaves as an accidental host in which Toxocara sp. does not become an adult worm. This infection is generally asymptomatic but clinical manifestations can be diverse, and they vary according to number and localization of entrenched larvae and host's immune system. In the last years it has been studied a relation between Toxocara sp. and some cutaneous manifestations. We describe the case of a 19-month infant with visceral larva migrans and cutaneous manifestations from vasculitis, explaining its form of presentation, evolution, diagnose and treatment.
