Cutaneous larva migrans (CLM) is a tropically acquired dermatosis that resolves spontaneously within 2 to 8 weeks. Rare case reports have been published in which the eruption persisted for up to a year.1 Herein, we report such a case.
A 36-year-old healthy white woman presented with a 4-month history of intense pruritus on the right plantar surface of the second toe, which began 2 weeks after returning from Jamaica where she walked barefoot on the beach. Within weeks, the pruritus spread to involve the third and fourth toes and eventually the plantar surface of the instep. She denied the presence of vesicles, papules, or a serpiginous rash. She claimed that her symptoms waxed and waned and that she experienced several week–long periods with no symptoms or visible rash.
