Wells syndrome triggered by toxocariasis

Wells syndrome is defined clinically as recurrent erythemaotus plaques and histologically as diffuse eosinophillic infiltrate with characteristic flame figures. This disease is thought to be a hypersensitivity reaction to certain triggers such as insect bites, drugs, malignancy, infections/infestations including parasitic infections. Toxocariasis and other parasitic infections can present with Wells syndrome clinically and histologically. Toxocara canis is a common round worm that can causes visceral or ocular larva migrans.
