Cutaneous Larva Migrans.

Sir,

Cutaneous larva migrans is a characteristic serpiginous skin lesion which may be seen in travelers. The most common causative organisms are Ancylostoma braziliense and Ancylostoma caninum.[1]

A 49 year-old male presented to the office complaining of a rash on his legs. The patient had recently spent 5 days in Florida moving lemon trees. Five days after returning to his home in eastern Pennsylvania, the patient noticed a rash on both legs. Examination showed multiple red, raised, serpiginous lesions on his lower legs [Figure 1]. The patient was started on ivermectin orally for 2 days. He was reevaluated after 3 weeks. The rash had improved significantly, the serpiginous lesions were fading, and pruritus had disappeared [Figure 2].
