Cutaneous Larva Migrans - Symptoms and Treatment

Cutaneous larva migrans is a parasitic skin infection caused by hookworm larvae that usually infest cats, dogs and other animals. Humans can pick up the infection by walking barefoot on soil or beaches contaminated with animal feces. The hookworms that cause the condition are small, round blood-sucking worms that infest about 700 million people around the world. Cutaneous larvae migrans occurs most often among children, those who crawl beneath raised buildings, and sunbathers who lie down on wet sand contaminated with hookworm larvae. It most commonly occurs on the feet, legs, hands and buttocks. Cutaneous larva Migrans causes intense pruritus; signs are erythema and papules at the site of entry, with a winding, threadlike subcutaneous trail of reddish-brown inflammation. Diagnosis is by history and clinical appearance. Topical thiabendazole 15% liquid or cream (compounded) bid to tid for 5 days is extremely effective. Oral thiabendazole is not well tolerated and not usually used. Albendazole and ivermectin can be curative and are well tolerated. CLM may be complicated by a self-limiting pulmonary reaction called Löffler's syndrome (patchy pulmonary infiltrates and peripheral blood eosinophilia).
