CUTANEOUS LARVA MIGRANS
Cutaneous larva migrans (CLM) is an infestation by a nematode, most often the animal hookworm(Ancylostoma caninum or Ancylostoma braziliense), less often the human hookworm (Ancylostoma duodenale and Necator americanus).
CLM occurs most commonly in areas with warm climates such as Africa, Asia, Latin America, and the southeastern United States. It is the most common travel-related skin disease, often occurring in travelers who have visited these areas.
Pathophysiology and Natural History
CLM is a self-limited disease, invariably acquired when the skin has contact with sand or soil contaminated with animal feces. The feet are the most common affected site, and the legs and buttocks are less so. Left untreated, the disease resolves within a few months.
Signs, Symptoms, and Diagnosis
Affected patients have itchy erythematous, serpiginous tracks, usually on the feet, buttocks, or thighs. The track advances 1 to 2 cm/day.
The history and pattern of skin disease (serpiginous tracks) and its location should suggest the diagnosis.
CLM must be clinically differentiated from migratory myiasis and cutaneous larva currens. Migratory myiasis extends more slowly; the fly larvae are usually larger and survive longer. Cutaneous larva currens is the infestation with the roundworm Strongyloides stercoralis. The sign is pruritic, serpiginous, erythematous tracks on the perineal area, buttocks, and thighs, which evolve rapidly at a rate of 5 to 15 cm/hr. This differentiation is important, because cutaneous larva currens may be associated with systemic or disseminated infection with a mortality rate of up to 70% to 90%
Several treatment strategies exist. The most common treatments are thiabendazole cream 2 or 3 times a day for 5 to 10 days, albendazole 400 mg orally daily for 3 to 5 days, and ivermectin as a single dose of 12 mg (200 mcg/kg).
