CUTANEOUS LARVA MIGRANS
Cutaneous larva migrans (CLM) is the skin disease most commonly contracted by travelers returning from tropical countries; however, unlike most tropical parasites, CLM is also endemic in the United States!
CLM is the clinical syndrome that results when humans are accidental hosts to dog or cat hookworms. The accidental parasites are unable to complete their life cycle in the human host and instead remain in the cutaneous dermal layers as larvae that migrate aimlessly about producing the raised, itchy, red, tracks that are characteristic of cutaneous larva migrans.
