Cutaneous larva migrans in Adult
Clinically, the cutaneous findings are characterized by intensely pruritic serpiginous tracts localized primarily to the ankles and feet; however, other areas of the body that have contacted infected soil may be involved. Itching begins within hours to days of exposure, and migration usually occurs after 4 days. Lesions are often edematous, erythematous, and may have associated vesicles and bullae. The majority of patients present with more than one lesion. Migration of larvae begins approximately 4 days after entry and then progresses horizontally about 1-2 cm daily. Since the human is a "dead-end" host, the larva typically spontaneously resolve, although lesions may persist for up to a month. Treatment is often undertaken for relief of intense pruritus and the possibility of bacterial superinfection. The disease is most commonly found in warm climates, with high incidence observed in the southeastern United States, Central and South America, Africa, and the Caribbean.
Although rare, larvae can migrate beyond the skin, causing systemic disease characterized by pulmonary infiltrates and peripheral eosinophilia, termed Loeffler syndrome.
