Cutaneous Larva Migrans With Parts of the Larva in the Epidermis

Creeping eruption is usually caused by hookworms, most commonly Ancylostoma braziliensis and Ancylostoma caninum. Because lesions of cutaneous larva migrans have a typical clinical appearance, they are rarely biopsied. Specimens usually show spongiotic dermatitis with spongiotic vesicles containing neutrophils and eosinophils and a mixed-cell dermal infiltrate with numerous eosinophils. We report a case with parts of the larva migrans in the epidermis on histologic examination.
