Abstract
We describe a case of Henoch-Schönlein purpura in the onset of Toxocara canis infection. The diagnosis was made in a 17-year-old boy based on the association of palpable purpura, oligoarthritis, acute abdominal pain, microhematuria, and cutaneous vasculitis. Toxocariasis, suggested by hypereosinophilia and domestic contact with a puppy, was confirmed by anti-Toxocara IgG and IgE and Western blot. Complete spontaneous resolution occurred within a few days. Transient presence of antinuclear antibodies and the absence of larvae in the skin biopsy favor an immunologic parasite induced disorder. A hypersensitivity vasculitis to Toxocara canis is suggested.
