A business traveller returns from Papua New Guinea complaining of extremely itchy feet for the last 3 days. He has tried a variety of moisturisers, herbal ointments and home remedies, but none have helped at all. He has used no new skin products or washing detergents, and he has no prior skin conditions. He says he spent time in a forest camping and sunbathing on a beach whilst he was abroad.

On examination, you notice some red spots with associated surrounding swelling and signs of excoriation. Blood work reveals a marked eosinophilia.
